I feel like there's an argument to be made that
the images are a derived
work from the data itself, so it may be best to just stick with OSM's
license rather than run into any possible issues. (Also, of course, I am
biased and prefer copyleft licenses since they support free information.)

What is the license for the map tiles, i.e. the
cartography rather than
the data? Open Street Maps uses CC-BY-SA, although they don't really make
it clear who is supposed to be attributed. It looks like our tiles are
different though.

We'd love for you to try our new service, experiment writing tools using
our tiles, and giving us feedback <
https://www.mediawiki.org/wiki/Talk:Maps> .
If you've built a tool using OpenStreetMap-based imagery then using our
service is a simple drop-in replacement.
Getting started is as easy as
https://www.mediawiki.org/wiki/Maps#Getting_Started
How can you help?
* Adapt your labs tool to use this service - for example, use Leaflet js
library and point it to
https://maps.wikimedia.org
* File bugs in Phabricator
<https://phabricator.wikimedia.org/tag/discovery-maps-sprint/>
* Provide us feedback to help guide future features
<https://www.mediawiki.org/wiki/Talk:Maps>
* Improve our map style <https://github.com/kartotherian/osm-bright.tm2

Kartotherian
can
produce tiles as images (png), and as raw vector data (PBF Mapbox
format or json):
.../{source}/{zoom}/{x}/{y}[(a){scale}x].{format}
Additionally, Kartotherian can produce snapshot (static) images of any
location, scaling, and zoom level with
.../{source},{zoom},{lat},{lon},{width}x{height}[(a){scale}x].{format}.
For example, to get an image centered at 42,-3.14, at zoom level 4, size
800x600, use
https://maps.wikimedia.org/img/osm-intl,4,42,-3.14,800x600.png
(copy/paste the link, or else it might not work due to referrer
restriction).
Do note that the static feature is highly experimental right now.
We would like to thank WMF Ops (especially Alex Kosiaris, Brandon Black,
and Jaime Crespo), services team, OSM community and engineers, and the
Mapnik and Mapbox teams. The project would not have completed so fast
without you.
Thank You
