Can't speak for anyone else, but mine still works fine. Just tested by disabling my NIC and tried several games. SP only games didn't even mention that I'd gone offline, Skyrim told me that it couldn't connect for a cloud sync and warned me that I wouldn't be able to use progress from another system, but it still ran fine when I said 'okay'. It swapped from online to offline through the manual switch fine, and halted (as expected) when trying to swap back online manually before I enabled my NIC again.

Anyways, point is, it's definitely not some sort of policy change. It has to be a bug or something interfering with it.
