I think it comes down to just knowing what is good. When you're young you don't have any experience to judge quality by. As you get older you can rapidly assess that something sucks, even if other people are pumping it up. Either in terms of gameplay or plot or whatever, now you have standards. Also, a lot of modern games just don't respect your time, and as you get older you realize your time is valuable so you just don't have the patience for that.
I'm in my 30s, I still game, but I'm a lot quicker to just go "this sucks" and move on to something else.
I think these rules are intended to be malicious. If you want to make it hard for people to organize but just banning them is illegal, the next step is to just make it super uncomfortable for them to hang around, so, no water.
