Well, that would indeed be a huge point in favor of CC0 then. Unfortunately, I'm not aware of any way to turn that into a measurable analyze, as too many factors might come coincidentally to this. However, since you are contributor of many open database, maybe you are aware of some studies on the subject which can back your opinion.Dear Mathieu,

I forward here the message I initially posted on the Meta Tremendous Wiktionary User Group talk page, because I'm interested to have a wider feedback of the community on this point. Whether you think that my view is completely misguided or that I might have a few relevant points, I'm extremely interested to know it, so please be bold.
As having contributed to many open database and as user of many open database, the CCZero is my default choice for making data open. Adoption of this license is, IMHO, the prime reason Wikidata is growing so fast, and integrated so fast in many use cases.
Well, surely my message don't help to make it obvious, but I'm not radically against CC0, and don't deny it does have huge advantages in reuse. As an example I already gave the CC0/public domain for works publishd by State institutions. This is something that I am completely favorable to and will defend and promote anytime I can.License incompatibilities have been a major concern in open source development and academic research. Yes, there too, there is a continuous almost-religious and unsolved discussion about copylefting, but the plain experience there is that the closer to the idea of public domain, the easier it is to use. The advantages of CCZero have been widely discussed in the life sciences, and while not everyone choice, the benefits outweigh the disadvantages for many.
I'm not sure what you mean here. If you are talking about things like pictures that the NASA release, I think it falls in the case exposed above. If you are speaking of the most used license on Wikimedia by benevolent contributors, I'm not aware of the statistics on this topic, but would be interested to have some.I also note that public domain (which CCZero formalizes across jurisdictions) is still the "ideal" license when uploading images to Wikimedia, suggesting more of Wikimedia actually finds the CCZero idea very welcome.
I guess it's all in your honour.Also stress that in no way I recognize myself in your comments about Denny and Google.
If you mean "freedom of one begins where it confirms freedom of others", it's not "my" definition, however I could not give proper credit to it. Maybe Joseph Déjacque was among the first to publish this with some variation in the exact formulation. But really this not "mine definition". Also it is of course not the ultimate definition of freedom that everybody have to agree with.And your comment that "freedom of one is murder and slavery of others" needs some refinement, IMHO; my definition of "freedom" is quite different and I experience your definition as abusive and offensive.
The CCZero license of Wikidata is essential to my contributions and use of Wikimedia products. The chemistry knowledge in Wikidata is 100x more useful (to me) than that in Wikipedia etc. That is in part because of the machine readability, but also to a large part by the choice of CCZero.
I hope this helps,
with kind regards,
