There's a right way and a wrong way to do telemetry.
The right way: When the Windows 7 RC was released, you guys made it available for free, with telemetry, as the final stage of real-world testing. It was up-front, it was open, it was optional. I was happy to join in, and bought Windows 7 when it came out, and it good.
The wrong way: When Windows 10 was released, a whole lot of nebulously defined, mandatory telemetry was baked into the commercial release. The fact that it was "free" is irrelevant - this was a clear transition from "you own the software" to "MS, via the software, owns and monetizes you." Then the "Get Windows 10" push started and for over a year we had a pitched battle between MS trying to force users to upgrade, and users who didn't want Windows 10 with all its invasive marketing, telemetry (weird how that slider keeps changing itself back from "minimal" to "full", huh?), and loss of control of their systems. I've disagreed with MS's customer relations in the past but never before have I felt that they were actively hostile. I will never use Windows 10.
