Mozilla income went from $78m to $497m. It's a much bigger organisation to before. Also if you inflation rate the 500k pay, it's now worth $710k

The web changed, and complexity increased and even staying in there against a larger adversary is hard. Unless you run a company that is competing with Google, I don't think you're really qualified to comment.
Edit: Just realise your description has "Fuck Mozilla!" and you've been bashing it since you started on Lemmy. Looks very shilly to me.
