You all remember just a few weeks ago when Sony ripped away a bunch of movies and TV shows people “owned”? This ad is on Amazon. You can’t “own” it on Prime. You can just access it until they lose the license. How can they get away with lying like this?
If they’re saying “own” on their advertisements then they should be required to refund you when they eventually have to take it away. I’m pretty sure “ownership” has a legal definition and it’s probably not too ambiguous.
It should at least be considered false advertising if they can’t guarantee access permanently.
