You can say no it's not what happened happened all you want. But here's the announcement from the libav side[1]. It was definitely not a friendly fork. There was clearly a dispute and the Niedermayer side won[2], which led to the fork. But either way Niedermayer was basically BDFL since he took over from Fabrice Bellard until he resigned. That is ultimately one of the things that led to the dispute. Much like what happened between vim and neovim. Although the disagreements between Bram and the neovim team were a lot more friendly. I'm not sure which part you disagree with, since you clearly seem to be saying the same thing with respect to who forked what. And one of the big fundamental differences between ffmpeg/libav and thunderbird/betterbird is that the Niedermayer side still merged in a lot of changes from libav, leading to an overall better product than libav, whereas thunderbird does not at all follow the same behaviour WRT betterbird. They have ridiculous bugs that had for decades and as much as I try to like it I can't for the life of me for example understand how they have an open request for a search that doesn't end up in that stupid filter view instead of just showing all results.
