Also wrong. The telemetry in Windows 8 was just in critical components that had been instrumented long ago, such as Windows Update, crash management, etc. None of those were using the current universal telemetry system. In fact, I don't know if all of them moved to the new telemetry infrastructure shared with the rest of the OS or if they kept what they had and just added the new telemetry on top.

All that said, I agree with your last point about upgrading being a fair compromise compared to staying in Windows 7 or gasp Windows 8.
