Mozilla has occasionally seemed to have inconsistent values/behavior, for a long time, which has made me nervous. But some of their stuff is still the best starting point for some public interest technology goals. So I keep working with it, and promoting it (though not as strongly as I have in the past).
I've suspected that their mix of people includes (but not limited to):
* many very capable true-believers in their ostensible mission, like we'd expect of Mozilla (though they can't all have perfect morale right now);
* some people who've gone through, or are going through, a rough time, and are trying to use Mozilla to solve problems that they see elsewhere in the world (even if off-mission, but other people are sympathetic and want to help, so it's complicated);
* maybe some true-believers who have to make hard compromises to keep Mozilla alive, somewhat quietly (and maybe it's hard to know which compromises to make, and to not lose the way at some point); and
* people who'd actually much rather have their counterpart roles at a FAANG or other prestitious tech company (and so aren't true-believers in the mission, and will tend to think and act with their true thinking, with impact to vision and decisions, and to leadership of the true-believers).
Maybe some key people span multiple categories.
This isn't a satisfying grand unified theory of all of Mozilla's behavior, and I'm sure there's insiders with better insights.
