In fairness, a lot of "digital distribution platforms" or online services do this as well.
Prime examples I've seen:
Google closing someone's account for using not their real legal name on Google+, locking away access to his music, documents, e-mail, and photos, all of which he'd migrated to his Google account.
Steam closing someone's account and basically cancelling a thousand dollars of "purchased" games because he broke their ToS, which makes you wonder what the difference is between purchasing and purchasing (via Steam) when the price is the same but your recourse is not.
