I would argue that since they knew you were giving them access on the assumption that they would not do things like that, you would have grounds to complain. Similarly, I installed Firefox on the understanding that it would not phone home with opt-out telemetry, advertise third party products, or syntergise with acquired properties. Mozilla has, in the past few months, done all three.

I like Firefox, though, so I'd rather kick the tubas out of Mozilla than go kick them off my individual installation. Does the public have any power over Mozilla's governance?
