Folks,
Here is the summary of the votes I received in answer to the request to switch to a copyleft-style license:
Agree Disagree Indifferent
All votes: 76 (70%) 15 (14%) 17 (16%)
Contributors: 39 (66%) 7 (12%) 13 (22%)
Contrib. weighted: 59 (64%) 13 (14%) 20 (22%)
The first line counts all the votes I received. The second line counts the votes of all people/companies who contributed some code to the project. The last line counts all contributors again but with each being given 1, 2, or 3 votes depending on the importance of his contributions (this evaluation is obviously a bit subjective, but I think the overall trend is clear).
The obvious result of this vote is that my previous conclusion was wrong: there is clearly widespread support in the community for a copyleft-style license. With 2 out of 3 contributors in favor of the switch, and less than 15% opposed to it, it's clear that we are going to proceed with the change.
We now have to decide the implementation details, like the exact license used, whether to require copyright assignments, etc. My suggestion is that we create a separate mailing list to discuss that, to avoid drowning wine-devel under yet another license flame war.
