Is this really for a "purchase"? Seems to me it's pretty fundamentally fraudulent to offer for purchase something without the authority to sell it. This means that, at any time, any movie you "purchased" can be removed from your library indefinitely, without credit.

Until now I haven't had a problem paying for content, however if the rights of a purchase have been eroded this much, my mind is changed.
