The mental gymnastics are in response to copyright holders' gymnastics. They remove content, relocate it, put it behind tiered subscriptions, or sometimes effectively delete it from all legal avenues after owners/subscribers paid for it. So if paying for a subscription isn't owning it, as described in Amazon's fine print for example, then what do you do? It's a long-term rental subject to removal upon any licensing transfers. Sure, we get greedy once set up, but if legal options don't actually offer you any legal ownership due to legal gymnastics, then yeah, I'll do the mental gymnastics right back at them.
