What can I say, I always had a feeling that apple hates open source and likes to block open source devs in all possible ways, this just ensures me in this feeling. One more reason for me to be happy not to have to work with their products. On Sat, Feb 7, 2015 at 9:36 PM, Amir E. Aharoni <amir.aharoni(a)mail.huji.ac.il> wrote:

TBH as open source developer I don't feel like publishing kernel sources makes it any easier for me to create applications for their platform. If I want to create an application for android, I can download android studio and run it on Windows, Linux or Mac. The studio itself is open source and programs are easy to package. If I want to create an application for iPhone, I have to own a Mac, because even if I wanted to buy OS only and install it on non-apple hardware, it wouldn't work and xcode is not available for any other platform than Mac. This is blocker for any open source developer who wants to create non-profit software and isn't willing to put money into something that is never gonna be useful for them, so that they can create software that others can freely use. This is case of all apple products, even if I wanted to create a program for Windows, which is commercial platform, I can easily do that on linux and compile with mingw compiler that can build .exe files on linux.

It also has it here http://www.gnu.org/licenses/rms-why-gplv3.html on reasons why to upgrade version 3.   On Saturday, 7 February 2015, 22:21, Tyler Romeo <tylerromeo(a)gmail.com> wrote: I’ve been meaning to make this thread for a while. I also believe we should switch over to GPL 3. == Reasons to switch == First, to address the reason of why, there are a couple of reasons. Reference: https://www.softwarefreedom.org/resources/2014/SFLC-Guide_to_GPL_Compliance… === Language changes === Much of the language of the license has been rewritten or changed. Specifically so that: a) it is more international and not using US-specific wording (e.g., “conveying”); and b) certain things have been clarified due to changes in the Internet and technology over time.  As an example, GPLv2 requires that when distributing software that the source code be provided *on a physical medium*. The GPLv3 relaxes this and allows an offer of providing source code via network transmission, as we are doing right now. === License compatibility === The GPLv3 was adjusted so that it is compatible with more free software licenses. The Apache 2.0 license and the XFree86 license are only compatible with the GPLv3, not v2. === Termination upon infringement === This is actually a pretty important one. The GPLv2 has a clause that upon a licensee violating the GPL, their entire license is immediately terminated, and may only be reissued by the licensor. This is obviously a troublesome legal situation in FOSS projects because now a licensee has to seek permission to use the software from the possibly hundreds of contributors, each of whom is an individual and independent licensor for the software. In GPLv3, this is fixed by allowing infringers to resume distribution of the software if they cease all violations. In other words, while the copyright holder can still, if they so desire, explicitly terminate the license after a violation, in most cases the licensee can make remedies and automatically continue distribution. === Addition FOSS protections === As other people have previously stated, the GPLv3 adds additional restrictions to protect against trademark law, patent law, and sub-licensing. I won’t go too much into it, because I don’t know the details, but it basically is an attempt to prevent the aforementioned from imposing additional restrictions on redistributors. == What MediaWiki should do == === Changing our license === Just to specifically address the process that would be involved, all our current code can be licensed under the GPLv2 or any later version. Thus it would be trivial to just “redistribute” all of the code under the GPLv3. Yes, all the original code would still be licensed under the GPLv2 as well, since that was what it was contributed under, but any copy obtained from the Wikimedia Foundation would be under v3 since that is what the WMF would be distributing. In addition, by doing so we’d require all further changes to be contributed under the GPLv3 or a compatible license, which, as aforementioned, is actually more licenses than could be done under the v2. === Which license? === I’m going to be honest, I think it is non-controversial to change over to GPLv3. It isn’t really more restrictive than v2 (patent law and DRM don’t really apply to us). If anything, it is actually an easier-to-implement license, since now the WMF has less responsibilities in terms of source code offering, etc. **However**, I’d like to take this opportunity and jump a step further. What would everybody think of switching to the AGPLv3 instead? The advantage that this provides, for those who don’t know, is a single additional restriction: when the software is used over the network, source code must still be provided. In other words, the requirements all remain the same (providing a copy of the source code, ensuring all modifications are also GPLed, etc.). The only difference is that the requirements take effect over the Internet rather than only when the software is distributed in object code form. The situation this protects against specifically is if a vendor does the following: 1) Download MediaWiki 2) Make a change to the software that they want to keep secret 3) Run the new MediaWiki on their servers, but never give out the source code Technically, this is compliant with the license, because a distributor only has to provide corresponding source code if a user is given object code, which in the case of a web application, they are not. The AGPL protects against this by requiring provision of source code to the end-user web clients. Of course, the source code can be “provided” in the form of a simple link to another website on which to download the code. --  Tyler Romeo 0x405D34A7C86B42DF On February 7, 2015 at 16:08:16, Bartosz Dziewoński (matma.rex(a)gmail.com) wrote: MediaWiki is already available under GPL 2 *or any later version*.

The GPLv3 is not more restrictive. As I mentioned, if anything it’s more permissive, since it is compatible with more licenses, and because it allows distributors to add some certain additional clauses to the license at their discretion. If a developer wants to release their personal code under the Apache 2.0 license, they can do so and still contribute to MediaWiki. Or if a distributor wants to offer their own warranty on MediaWiki, they can. Maybe it was a little presumptuous of me to bring up AGPL, because I’ll admit I even have bad feelings about it, especially considering the whole security patch issue. However, if somebody would like to offer up an actual reason for why upgrading from v2 to v3 is a bad idea, I’m all ears.

Hi! I'm in the free software world for more than two decades now, and I still fail to understand why this scenario bothers people so much. There are a number of projects that do exactly that, on top of various free software projects (both non-GPL and GPL), and so far I've not seen much problem coming out of it. Let's assume for a minute that we live in a nightmare world where there is a company, say EvilWiki Corp., which improves mediawiki somehow and sells the result. How exactly life in that world substantially worse for us than in ours where EvilWiki Corp. does not exist? It is true that GPL is a response for that. What I am less sure about is that it is the *right* response. There are dozens major successful open source projects that have permissive licenses, or hundreds if you relax the criteria of "major" somewhat. I have hard time remembering one of them that seriously suffered from the nightmare scenario as you describe - maybe there are, but if there would be many, I'd probably hear about them, so I assume such cases, if existing, must be rare (or I am exceptionally ignorant). Some time ago, open source was a weird phenomenon with a shade of crazy - what do you mean give your code to everybody for free? Isn't that some Communist plot? I assume in these times adding some legal power to the movement was a very enticing prospect. Now, open source is a proven thing, everybody does it - Apple does it, Microsoft does it, IBM does it, Google does it, everybody who's anybody does it. It's in fashion. You don't have to force people to follow the fashion. So I wonder if spending time worrying about if the license is strong enough and defensive enough is something worth doing now. -- Stas Malyshev smalyshev(a)wikimedia.org

Hi Tyler More comments inline: On Sun, Feb 8, 2015 at 6:11 PM, Tyler Romeo &lt;tylerromeo(a)gmail.com&gt; wrote: MPL v1.1 was not compatible with any version of the GPL, hence the reason why Mozilla eventually multi-licensed their software under MPL/GPL/LGPL (they pioneered the approach, IIRC). MPL v2 achieves GPL compatibility by specifically naming GPL v2+, LGPL v2.1+, and AGPL v3+ as "Secondary Licenses", and then optionally allowing relicensing (i.e. one-way conversion of the software to GPL/LGPL/AGPL) under section 3.3. It basically bakes multi-licensing into the license itself. By this logic, once MPL-licensed code is relicensed under GPL, you cannot go back to MPL, so the only way to add GPL code to an MPL project is if the entire project is GPL. The fact that there's an option to upgrade the license to GPLv3 is sufficient for GPLv2+ code to be compatible with Apache 2.0 code, in the same way that the option to relicense MPL code as GPL code is sufficient for GPL compatibility. You don't need to actually perform the relicensing, you merely have to offer the licensee the option to do so if they so desire. Thanks for clarifying that. I think my experience is more-or-less in line with Stas, though I think I still have more sympathy for the copyleft approach than he has. I see the copyleft/permissive choice as more of a tactical than a moral choice, and that I think permissive is going to be a more effective long-term tactic to achieve the moral goals also sought by proponents of copyleft. Downstream modifiers of software eventually learn that keeping secret patches to upstream code is more hassle than whatever "secret sauce" benefits they get. Also, one cost of copyleft licenses is that they are much, much more complicated than permissive licenses. Even though many people feel comfortable with the compliance requirements of most OSI-approved licenses, the permissive licenses can usually stand alone without an FAQ, whereas an FAQ is required for just about all of the copyleft licenses. That simplicity reduces a very real barrier to adoption. Rob

This entire conversation is a bit disappointing, mainly because I am a supporter of the free software movement, and like to believe that users should have a right to see the source code of software they use. Obviously not everybody feels this way and not everybody is going to support the free software movement, but I can assure you I personally have no plans on contributing to any WMF project that is Apache licensed, but at the very least MediaWiki core is still GPLv2, even if it makes things a bit more difficult. Also, I have no idea how the MPL works, but I can assure you that licensing under the “GPLv2 or any later version” cannot possibly imply it is available under both the v2 and v3. The different GPL versions have conflicting terms. You cannot possibly use the terms of the v2 and v3 simultaneously. It is legally impossible. What is means is that you can use the software under the terms of the v2 *or* the v3. And, as I mentioned, since Apache is only compatible with v3, as long as using the software under the v2 is an option, you cannot combine code that is under Apache. --  Tyler Romeo 0x405D34A7C86B42DF On February 9, 2015 at 04:06:54, David Gerard (dgerard(a)gmail.com) wrote: On 9 February 2015 at 08:28, Max Semenik &lt;maxsem.wiki(a)gmail.com&gt; wrote: Indeed, but they touted the mythical attractiveness of a permissive license over the bondage of copyleft.

I’m still not entirely convinced that the GPLv2 allows more licenses than the v3. Yeah, maybe in the case of extensions it’s OK, but I do not think it is possible to add Apache code into MediaWiki core and still allow licensing MediaWiki under both the v2 and the v3. Maybe if legal can provide an explanation, but at this point so many people are dying to use a permissive license that I doubt anything is ever going to change. Also, I understand everybody seems to be worried about using the AGPL in libraries because then the libraries cannot be used by outside companies in proprietary software. But at that point it’s really just a difference in opinion. What is more important: allowing as many people to use our libraries as possible, or protecting against our libraries from being used in proprietary software. --  Tyler Romeo 0x405D34A7C86B42DF On February 10, 2015 at 18:23:32, David Gerard (dgerard(a)gmail.com) wrote: On 10 February 2015 at 23:19, Bryan Tong Minh &lt;bryan.tongminh(a)gmail.com&gt; wrote: And is also infeasible.

They only need to do so if they distribute. There's lots of Apache2 projects that have a very large amount of contribution, so maybe this would happen, but I doubt it. Not having to maintain your own fork is a really strong motivator for most companies. - Ryan

Accepting Apache code into core should be treated the same as accepting GPL v3-only code into core. Both significantly restrict the licensing of the combined work. --scott

The set of acceptable core licenses is thus *more* restrictive ("GPL v2+" and those licenses compatible with it) so that our users have *more* freedom (license combined works under GPLv2, GPLv3, AGPL (maybe), etc). That's how it works. It's not hard. --scott

Hi! This is very plausible, as the decision to contribute is rarely driven by the license as a primary factor - you don't say "here's random GPL-licensed project, I don't know anything about its domain, language, goals, community, status or needs, but I feel compelled to contribute because it's GPL!" - or at least, most people won't say that. As long as the license is not completely un-acceptable, I would assume other factors would dominate such decision. However, I know cases where I personally had to write code or otherwise work around GPL libraries because of license incompatibility with other open-source projects. That, of course, can be also counted as "more contributions" but I don't think that's what you meant :) Out of curiosity, what evidence you mean? You must already know examples of successful projects under permissive licenses. So you probably seeking the examples of why permissive license solicits _more_ contributions that if the same project was under GPL. Such example would require a rather rare occurrence of a project changing the license while at mature stage and measuring the contributions before and after the license change, otherwise we'd be comparing apples to oranges. My personal opinion is, as I described above, that license doesn't matter too much provided it's not unacceptably restrictive. Thus, for me looking for such examples would be a waste of time :) -- Stas Malyshev smalyshev(a)wikimedia.org

In any case, as you state, the GPL as applied to MediaWiki is already very weakly copyleft, leaving us only the disadvantage of incompatibility with non-GPL projects, with the advantages of copyleft non-existent for the MediaWiki case.

You can use, at your choice either of them (or any later version not yet released). Though your options may be decreased if you combine the work with a different one not compatible with both of them. Also note we have traditionally held the position of not considering MW extensions derived works (and thus allowing them to be licensed like eg. MIT), which would be arguable. I wouldn't even be surprised if -supposing we had an AGPL mediawiki- a troll came requesting the full LocalSettings.php contents to be published, password DB included. I also vote for maintaining the current GPLv2+ license.
