My understanding is that they are all under Mozilla and they’re all in danger of the same business decisions.

If that’s not the case I’d be more than happy if someone could prove me wrong.

I’ve already moved most of my stuff to forks or different software altogether.

Firefox -> LibreWolf and Waterfox

Thunderbird -> Evolution

I’m still trying to decide if I want to move off k9mail on mobile to something else. I probably will but I’m not sure what at this point.
