People are too worked up about how this started over "porn games getting banned," and it's a rather disengenuous way to loom at it.
This started primarily due to two factors:
1. With X not being a censorfest ever since Musk decided to turn it into his personal chatroom, communities and discussion vectors have been better established to discuss shit like this among a wider group of people.
2. The payment processors decided to shit all over a company that is considered one of the last good companies, Steam (whether you personally believe this is irrelevant), and forced them to do something they didn't want to.
Every other time the payment processors have done this shit it was to people too small or isolated to get traction, and much of it was done when the only place to discuss it with a decent userbase was maybe 4chan if the mods decided to not be fags that day.
The current events are just a perfect storm, made even worse due to Steam changing their policy to state games that possibly go against payment processor TOS will be banned. It's not solely because some heavily taboo porn games were banned. It's because Visa essentially shot a guy in cold blood in a crowded street, and when people went WTF, they were like "nah it's cool, the government gave me permission to kill people I don't like."
