I'm with you on the first one and that's the closest reason why you could call Firefox payment "ad money". But the rest are not too strong. Google makes a lot of non-ad money too, even if it's a smaller portion than ads. You don't call airlines "banks" just because they make all of their money from currency-like "miles", and even fly at a loss [0].
What I want to say is that calling it "ad money" makes Firefox look bad when it shouldn't.
