(Reposted in here because this is the more correct section.)
So the situation is this: I run a project which is a fork of an emulator licensed under GPL v2, my fork respects that and has not changed the license. Last year, a contributor joined my team and then this year, he quit the team due to a disagreement. He then forked my project.
Now the things he did that I am concerned about are two:
1. He relicensed his fork as BSD 3-clause, keeping individual GPL v2 licensed files GPL v2, but changing the overall project license - is that allowed?
2. On his fork's website, he is distributing Linux binaries of his fork but has to this day not released the source code of the Linux-specific parts, claiming on his site that he is going to as soon as he deems it ready for release - is that allowed?
Looking forward to the answers, thanks in advance.
