That's already happening with facebook (oculus) and google as well (what happens to your android device? what about the photos you had stored on the cloud? what about all the sign-in with google?)
Don't see any lawyer field day yet.
Oculus is an extremely niche product, barely out of the experimental stage.
Can you point to cases where people have been locked out of their Android phones?
If so, I’m surprised lawyers aren’t involved.
It’s not clear though, what this has to do with app stores.
If we think companies shouldn’t be able to lock us out of their products for speech violations, that seems like an important consumer protection that should apply to all companies.
That is a fictional what if.
More importantly, it would be a field day for lawyers.
