You generalized the frustrations to being only with the game industry.
It’s generalized frustration with being constantly ripped off, so because people are already feeling that, of course they’re going to speak up about specific instances.
And your last point, again, getting ripped off is a problem everyone deals with. Rich or poor. If seeing too many opinions is a problem to you, maybe you should get off the internet. Don’t try to make this someone else’s problem.
If you don’t want to hear everyone’s opinions, you don’t have to, but that doesn’t mean they’re invalid or somehow “not a real problem” because they don’t align with your lifestyle or opinions.
