Unfortunately the term purchase for digital acquisitions is misleading. If I purchase a dvd I can lend it to my family, I can pass it on free to a friend to watch, or I can sell it second hand. If I don't dispose of it, it's mine for life.
That just doesn't apply to these digital acquisitions which are tied to the account and which the terms do allow to be revoked.
They aren't purchases but more like very long term rentals. Of course fewer people would spend money if they were told the truth so the media companies misleadingly say "purchase". (And since they all say purchase it would be very hard for one to break rank).
It's why something like Netflix of Kindle Unlimited can work well, at least you know you are spending an amount each month for basically unlimited access to the catalog.
