I'm personally a fan of fewer restrictions on content in video games and fewer "gatekeepers" but it's kind of inevitable that people would get upset when you chose to allow people to sell games like "Sex With Hitler" and "Pimp Life: Sex Simulator". Deciding to allow that content on your store and simultaneously not going to bat for it is weird, it's like they decided to just get the porn money while they could as a short-term boost to revenue.
Itch.io still has fewer restrictions but I assume they'll eventually have to clamp down too once payment processors cut them off - they don't have the financial resources to fight it like Valve or Epic do.
Interestingly Nintendo has as of late relaxed their restrictions too, you can find porn-adjacent shovelware on the Switch eShop despite their history of being very censorious. I wonder if payment processors will successfully push them around too or if Nintendo is too big to get pushed around.
