A lot of the content that is now shadowbanned is LGBTQIA+.
Not that it should matter, as this a massive overreach either way. Cultish censorship groups should not be dictating what type of completely legal things can consenting adults purchase for themselves. Be it violent content, taboo content, or LGBTQIA+ content, or anything else, as long as it is legal.
Of course, the most power here lies with the payment processors, Visa and Mastercard, who have a duopoly and can pretty much ban and destroy whatever they want for whatever reason they want. The consquences of this in the future are terrifying and reach far beyond just entertainment. They can pretty much bankrupt any company they want that doesn't do what they want, they can destroy any political capaign or party they want to, their power is completely unreasonable.
Currently, it is an awful look for Visa and Mastercard, who are abusing their duopoly position. It is also an awful look for Itch.io. Unfortunately, Visa and Mastercard are too large to fail, and will survive this abuse of power, but Itch.io will now slowly die due to this. This similar to what happened to Tumblr.
Edit: I saw a geat comment (by Marcus_Hallevy) in another thread that should have more attention:
"Those in the US. Contact your local representatives and tell them that in exchange for your vote that they should support Bill 401 and 987."
This is on point, and might be the only way we can really fight against the abuse of power by the payment processors. Petitions such as: https://www.change.org/p/tell-mastercard-visa-activist-groups-stop-controlling-w... are great at raising awareness to an issue, but ultimately they won't change anything by themselves, and can be safely ignored by large enough entities like the payment processors.
The only real way you can stop their abuse of power, is through legislative changes. And those bills such as ware mentoned in that comment are directly targeting this problem.
