Similarly-sized software companies are also overpaying their executives at the expense of worker wages, so Mozilla is right on track.
For countless years they've been handed some 400-500 million(!) for "free", just by keeping Google the default search engine. For a conventional company, this kind of money requires a massive operation, customer base, etc.
Mozilla just gets a check. Half a billion for free. And then pisses away this money on projects where most are questionable, have no impact, etc. All the while the user base shrinking further and further, for over a decade now.
If that is the situation, it seems pretty reasonable to me to just get rid of leadership altogether. Let the tech people figure it out, it's not like they can do worse.
