Thanks for posting this. The problem is though, I think we're all shy about fighting this because it's about something a bit... taboo. Like I'm not gonna tell my parents about this issue, or assume any nsfw devs are sending petition links to their friends. Mastercard has us by the balls here & I don't think enough people will complain.
You only need to mention that a group pressured these credit companies into the forcing steam and itch to remove games that have adult content and share your worried that if there allowed to continue doing this they will more than likely go after more and more media that as any adult elements like Witcher and mass effect since they have sex scenes from example eventually letting them freely take down anything they deem as negative or too sexual. Hammer in the fact that its not Adult games your worried about but the where this behaviour eventually leads and the consequences it would have on indie developers and gaming as a whole in the future.
Hey now, some of us are proud smut enjoyers. I made the guy at the Visa call centre take down that my complaint is specifically about their company and Mastercard having no place policing the pornography I choose to pay for and interact with. Even posted about it on my personal social media that has family on it, but then everyone in my life has known I'm a horny perv since I first got a TV in my room as a kid and suddenly had easy access to all the softcore tiddies a youth at the turn of the millennium could possibly desire.
They started with "adult" content. And immediately included LGBT content that had no overt sex in it. Just because...
It's about control and authoritarian censorship. And once they take enough stuff down, you actually start making children, teens and women even more susceptible to attacks and real world effects.
