I agree. And Mozilla somewhat addresses this in their second lessons learned: > [...] we need a mechanism to be able to quickly push updates to our users even when — especially when — everything else is down. It was great that we are able to use the Studies system, but it was also an imperfect tool that we pressed into service, and that had some undesirable side effects. In particular, we know that many users have auto-updates enabled but would prefer not to participate in Studies and that’s a reasonable preference [...] but at the same time we need to be able to push updates to our users Its a difficult situation to be in: Some users do not want any changes being applied automatically, but when something breaks, changes need to be applied. It sounds like the Firefox team is doing everything they can with respect to both ends of the spectrum.
