This argument of "we pay to find bugs in a game" is really strange. You talk as if you getting nothing out of this. Maybe you feel like that but I don't think it's true
"And we pay full prince too".
Yeah, it's frankly a stupid argument, because what people paid for is a full a game that will available later.
Playing the "early access" is the "preferential treatment" they get in exchange of forking the money in advance.
"We are paying to be playtesters when they should pay us for it" is also silly. Let's not pretend they weren't dying to try the game (and didn't complain when the EA was postponed too).
n fact no one ever forced their hand into the wallet. They are here because they want to.
