I think the point is that:

1. Yes Windows must have "approved" the drivers

2. Windows Update runs automatically and not (usually) manually

3. Automatic update can't even be disabled, only manually postponed a bit

At least 2 and 3 are different on virtually every Linux distro. Also, I find it very unlikely that they would accept such behavior.

To give MS the benefit of the doubt here, now that this happened and has been reported on they might decide to enforce stricter rules on manufacturers in the future. But as a Windows user you don't have a choice in case you don't like how they decide and how their decisions might change again later.
