Sounds more like a war against unsupported drivers to me, but I guess that's not evil enough to be true for you.

And turning on airplane mode is three steps at most (two if you're on the desktop). My laptop has a switch for it. It's also three steps at most on iOS, and the iPad doesn't have a supported way to use a wired connection either. OMG Apple are trying to kill wired networks!

EDIT: And how would it prevent breaking the connection, anyway? I can still unplug my router. All you need is an AP in the vicinity of the device and it's just as easy to pull as having a wired connection to the device itself would be. Unless you're proposing that MS also wants to install some kind of worldwide, pervasive, impossible to block wireless network (that's also free, because otherwise not paying your bills would still be a way to disconnect).
