Are there consumer computers that don't use the user's data at all when they're not in use?
The least they can do is to not load ads on the background. Sure, almost every device does some basic telemetry but showing ads is not something a device does need to function.
Telemetry is not something the device needs to function either. It's a "value add" in the best possible light, security breach in the worst.
Telemetry at least is useful for the developers to see how people use their software/devices/whatever.
Why should a user pay for something that is useful for a multi billion dollar multinational ad company?
