Mozilla's privacy branding is in direct conflict with Baker's vision of some kind of corporate entity that can pay her a lot of money. Apple can do this because they are filthy rich themselves, Mozilla's puny market share means that increasing their revenue will require them to use the most valuable coin in the Internet realm, which is user data.
I think a LibreOffice-style hard fork will be necessary at some point with a nonprofit carrying Firefox forward. Another thread mentioned Mozilla Firefox becoming a skin on Chromium ... Microsoft basically has validated this approach, and I can see Baker eliminating most of the rest of their engineering core to do the same.
