The whole Mozilla situation is even more of a scam than how the Wikimedia Foundation uses sob stories about paying for Wikipedia to get people to donate money to an entity which spends almost no money on Wikipedia... but, at least it does run Wikipedia! lol :/.
There is another interesting detail from your reference that makes it seem even worse to me: it says the CEO's salary is "paid only by a related for-profit"; at first, I was thinking "ok, at least the Foundation in fact is spending the money it is being donated (though, not on Firefox)"... but then I realized that means the Corporation is, in fact, spending $7m that it could have spent on Firefox.
