Less morally questionable than claiming to users they are "buying" access to media that can be revoked at any point in the future with no recompense, of course referring to Sony and Amazon.
PlayStation recently sent out emails regarding this, effectively reminding people that they did not, in fact, own what they purchased[0]. It's very confusing - someone here would have a much higher chance of knowing that it's not a direct purchase or right to ownership, though I'll bet most of the general public do not.
