Mozilla has their issues, but please don't undermine the good they are managing to squeeze out between the head-scratchers.
Whatever else I might say about Mozilla as an organization, the people who are part of it have their hearts in the right place. The ethical messaging is sincere.
I actually passed on an offer from Palantir when I went to work for Mozilla in 2010 (I left in 2015) and I never once doubted I made the right choice. With those two options I'd absolutely do it again, Mozilla management issues notwithstanding.
