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.
