I don’t have to play any mobile F2P gacha games, in order to know that they’re trash.
You do, actually. That's kinda the entire point of what I just said.
It is never okay to associate with gacha games, on any level.
Another strange confusion between "opinion" and "fact". Maybe you don't like gacha games; that's fine, but other people love them, and some of them probably think whatever indie arthouse gamejam game or whatever you find superior is actually trash.
People can spend their time and money however they want to. The fact that it seems to bother you is something that perhaps you may want to reflect upon, maybe isolate whatever insecurity you have that's causing this sort of disproportional reaction from you.
