The line is crossed. When we don't stop it now, this will be the end of privacy for every computer user -- at least of commercial OSs.

Even with the possibility to deactivate all this, the user consented to the "privacy terms" -- so the OS can even collect data "by error" -- and they will come away with it.

To trust such a company again, there would be a second set of privacy terms needed, that would be used for everybody that rejects the data collection. But I don't think, that there will be a second set of terms at all (for that to happen, a majority of people must start to think about their privacy).
