If you asked some random selection of technical people, "hey if Mozilla just went ahead and made a ToS which gives Mozilla a broad license to anything you enter into Firefox, then removed the text 'Mozilla won't sell your data' from their FAQ pages, how would people react?" I think 99.9% of people would've predicted that the reaction would be negative.
These things aren't as impossible to anticipate as you pretend. This backlash is 100% predictable, 100% Mozilla's fault, and 100% deserved.

But that's not what happened; that's the piling on. Mozilla says they will can use the data to do things that you request them to do.
