However, the reason I think it's only "kind of" pointless... it is in fact true that as far as I know, there is no way to pirate any of the "immersive" TV shows Apple has released. You can't watch them on any other VR headset, or even watch some 2D version on a flat screen.

Which means there are videos out there in the world right now which are immune from the analog loophole, at least as far as I know. It's a very small subset of all the content that has been produced, and it will stay that way, but it does exist.
