Licence and Legal FAQ/Why CC BY-SA is Unsuitable: Difference between revisions

<blockquote>

We would like to avoid someone like Google loading the whole of OSM into their Map Maker system, where Google then lay claim to any further improvements made by users. It is ok for them to load OSM, but improvements must then be shared back.

 

In such a case, Google would be required to distribute the rendered tiles under CC BY-SA, but they would be free to continue to use and improve the data without releasing it. This is a case which the community does not want to happen, yet it may be possible under CC BY-SA.
