Valve confirms credit card companies pressured it to delist certain adult games

Why do payment processors do stuff like this? Is there some regulation that requires them to? I get that they don't want to process fraudulent transactions, but I'd think the response to a higher percentage of fraud from some industry would be to charge them more. It doesn't make sense to me why they would be concerned about the content of games, as long as everything is legal and the parties concerned aren't subject to sanctions.

Some of these games seem completely abhorrent, and probably illegal in more restrictive jurisdictions, but not the United States. And I've not seen any suggestion they're funding terrorism or something. So I'm perplexed.

I suspect Valve is blaming the credit card companies for something they really wanted for themselves. Steam is a big store open to everyone and you’re going to scare away a big chunk of seniors, Christians, etc with stuff like incest, ageplay, and rape just so that a small minority uses you instead of…itch.io? Better to keep the big safe names like Being a Dik and Eternum on Steam and flush the rest so that you can have the best of both worlds.
