Context is important.

Some games are close to unplayable at launch, at least for some people. Some games have multiple game breaking bugs at launch, at least for some people.

Those games will likely be fixed within days or a couple of week, but if somebody pays full price for a game at launch, obviously they are going to be upset if the game is broken.

Some games repeat what other games have done before while offering a worse experience.

If I bought the patched version of such a game at a discount, my overall experience might be positive: but understandably, somebody who paid full-price and had issues with the game is going to be very unhappy.
