> Mozilla's decision-making is quite independent of Google's.
Mozilla certainly keeps the source of their funding in mind when making certain key decisions, in much the same way that elected officials do with respect to their donors. In fact, it's even more significant because Mozilla's funding primarily comes from a single source. And you can't just piss off your sole major benefactor without consequence.
The argument that they have the luxury to make independent decisions would be more plausible if their foundation were funded out of a legacy foundation or something like that.
Firefox on Android is an excellent browser. Firefox on iOS could be the same if Apple let go of its chokehold.
