That's indeed why it's taken down. Even recently I had an issue related to an external device that I thought was caused by the device. Turned out it was a Mac problem with a category of devices which didn't show this issue on any random Windows or even Linux box. I would never have known otherwise. It's clearly not in Apple's benefit for me to know this as it has lowered my opinion of their products.
There's not much other reason to completely take it offline.
