Mozilla rebranded itself as a "crew of activists". Browser is just a side business to generate revenue!
Is the whole issue not that they are less of a band of activists than they used to be. Now it is suddenly no longer about free and open source software, but more of means to run the whole machine, which is why they probably have profit oriented CEO as bad as that is.
IMO they need to be more a crew of activists than they are now. Fight against stuff like intrusion of AI in every single part of our lives and such.
They're not going to be able to make a case to Google that they need $500M annually to only spend on a browser. They're barely in charge of their own company.
They are probably a money laundy scheme this days. I used to donate every year to Mozilla. Of course, small ammounts because Im not rich. Today they would have to beat this money from my hands.
