And how exactly is the AI going to give Mozilla money? I mean not investor money, but actual profit? By alienating their moat userbase (privacy-minded technies)? Because if not for the AI haters, nobody would care about Firefox __at all__.

Funding end-user-facing FOSS is hard. An OS kernel or a DMBS can count on corporations that need new features providing funding. A browser can't. But then if small individual donations aren't enough for them (I think there's still no way to donate to Firefox directly?) they don't have a product.
