Honestly, I don't want to sound rude, but are you serious?
Do you think the subtle hint from Patreon (when they took the fuck out WiAB page) wasn't enough for someone whose business depends on these platforms? Almost all AVN developers were talking this year about that, that platforms will strengthen the implementation of rules for regulating adult content, since payment processors are putting pressure on them. They were talking about this last year too. Everyone who was curious about the topic could see where this was all heading.
And only resident "customers", like little children, do not see elementary cause and effect connections, for them it's a big surprise. And even now they continue to stomp their little feet here and there and demand "Let me fuck that loli-looking sister over there, Steam doesn't care anyway. What? No? Bad, bad dev, baka..." While Steam retires ~10-20 adult games a day, especially those that have any hint of I- or R-content in the title or description.
