Mozilla has always been the good guy, but only sometimes for technical reasons. They have been the good guy for their constant fight to keep the web open. They are the only for profit company that I happily give the benefit of the doubt.
Well, and they're hardly "for-profit". The Mozilla Corporation technically is, but the Corporation is wholly owned by the Mozilla Foundation, which is legally a Non-Profit, so is forced to invest their money into their specified mission.
Therefore if the Corporation makes more money than they feel like investing, they either have to put it aside for later investments or pay it out to the Foundation, which is then legally forced to invest it.
The only real thing where they could shove money to the side is with paying their workers too high wages.
