Both of those examples are short-lived. Nobody would be _confused_ by somebody saying that you can pay them for an "event" like riding on a bus or watching a movie, and nobody should be confused that a year down the line that event is no longer available. There's a qualitative difference between that and platforms saying that you've purchased something, letting you use it for enough years that it seems to be yours (like nearly everything else in your life you've "purchased") and then having that item taken away. Are you really arguing that the average person would believe that the library items they purchased could be taken away? If so, I'm clearly missing something, why? If not, that's the whole point -- we shouldn't use terms that actively mislead people into paying more money for fewer benefits.
