I believe exactly the opposite of this. I use Firefox in no small part due to ideological reasons (ie: I would use it even if it wasn't the best, just because I like the values they allege to stand for), and if they had let the CEO get a pass I would have literally uninstalled it and looked for something else.
im surprised people choose to use or not use firefox depending on the ceo.
the ceo doesnt take many decisions, the whole community does. some of them paid, and many unpaid.
by taking these - IMO - baseless decisions, you're only hurting the thousands of people putting their time, blood and tears without any commercial interest into firefox, not the ceo's you agree/disagree with.
remember that mozilla has no shareholders, the ceos dont get stock options, just a salary. its wholly owned by the mozilla foundation.
