Agree with John Doe

It's not like a car manufacturer tinkering with your car when you've locked it, it's like the salesman saying "You don't actually own the car, you are licensed to use it. We can come to your house and tinker with your car when we want. We don't have to notify you beforehand, or ask permission." before you buy it, and then whinging impotently, toys-out-of-pram style, when they do just that.

If you don't like it, get another OS.
