It's not based on a legal or technical guarantee. But it's based on what Sony did in the past:

P.T. ( https://en.wikipedia.org/wiki/P.T._(video_game) ) was pulled from the PS store. But Sony didn't make it unplayable if it was already installed. In fact, the wikipedia article says:

> After the cancellation, PlayStation 4 consoles with P.T. installed were listed on eBay for over $1,000
