I don't find this to be much of an issue because rarely is this ever a shock or surprise to the semi educated consumer. The game comes out and you see 100 people complain on reddit that it's buggy, so you just don't buy it until its resolved. Steam also has a pretty no fuss refund system for the cases you didn't see anything beforehand.

What seems to happen is people want the game as soon as possible but also complain when it isn't perfect on release but overall they enjoy playing it sooner more than they are bothered by its lack of polish.
