Right, I guess we agree but I was not clear.
In general, I don't care so much if Windows or macOS become as locked as Android or iOS, as long as I can install Linux on my hardware.
My point is that many people seem to complain because they want to be root on the Google-certified Android. I disagree with that: Google makes an OS where you cannot be root. If you want an OS where you can be root, you should be able to install another OS on the hardware you bought. Because you should own that hardware. But you don't own Google.
The problem is more that you're forced to use Google's OS. Usually just less convenient, but often in a literal sense too with these government services increasingly requiring attestation.
