I'm just disappointed about what Mozilla has become over the years. It wasn't supposed to be an "agile" tech company, with slick marketing and UI/UX, making deals to try to get market share.
It was supposed to be a non-profit foundation, making an open-source cross-platform browser engine, pushing for open protocols and standards. It enabled a few niche open-source operating systems to have a viable browser, it put a big dent in IE's market share, I would say it paved the way for Safari on iOS to be viable way back in 2009, and that obviously changed the world.
It still could have done that. It was making 100s of millions of dollars per year from the default search provider deal, for over a decade. It could have saved most of that money, spending it only on 50 to 100 browser engineers. Branching out to MDN and websocket or webrtc libraries would also make sense. But the rest of the crap, the marketing, the rebranding, the Pocket purchase and integration, Firefox OS, the voice recognition and AI stuff (and notice the announcement, they're keeping the AI division, really need that part apparently), stuff that nobody remembers, that's all a waste of money that could be saved by the non-profit foundation to just support the low-level engine keeping the open web viable.
