Maybe I'm just biased (as a OSS developer who has had my software ripped off), but I don't see he is trying to fix the problem. His first comment on the issue essentially was: "It does not violiate license of FFmpeg." Personally I'd be more then a little hostile against someone who started from that position.
If he was he'd do what he was advised to do many times in the issue tracker:
* Read the licences involved
* Hire a lawyer if he doesn't to understand it
* Follow it's terms
Argueing and tweaking things in his EULA isn't part of that solution. It's really not ffmpeg's position to offer him legal advice on how to comply with the licences.
If he genuininly believes he is following the licence, maybe he should talk to his lawyer about defamation?
But why bother having a wall of shame, if you're actively hostile to people who try to fix the problem?
