Yea, the telemetry one was kind of shady at the beginning, when it got turned on again after every update. That's changed a while ago though, and you can actually look through all the telemetry you're sending.
And you still cannot properly turn it off. Weird and invasive things still happen with large updates (bundled so you cannot pick and choose which changes are appropriate for you, such as security fixes only). The whole OS is a few quality of life changes that make it palatable to most people to deal with all of their frankly offensively invasive practices.
