So, here's the real problem. Patreon is, by a massive margin, the largest platform of it's type. Most devs that are on Patreon and SS have wildly lower SS numbers than Patreon. Like 3295 Patrons to 23 SS Subscribers. Asking the devs to give up Patreon for SS, and other small platforms, is asking them to give up 99% of their income.
The other issue is that it's not Patreon that makes the rules about content, it's MasterCard. MasterCard handles payment processing for Patreon, and enforces the censorship on threat of cutting off their services(which Patreon can't survive without). As a real nut kicker, MasterCard also handles payment processing for SS, BB, and all the other platforms. The only reason they don't enforce censorship on the smaller platforms is because "controversial" content makes up a much larger percentage of their profits, compared to Patreon. If MasterCard enforced censorship on SS, SS would not have enough content on their platform to pay the bills, and would shut down, so MasterCard turns a blind eye to them.
If Patreon did ban all adult content, and all the porn game devs flooded to SS, SS would no longer be able to fly under MasterCard's radar, and they'd be targeted just like Patreon. The only reason the loopholes, such as patches, and "choose your relationships" mechanics are mostly ignored by Patreon is because Patreon simply doesn't care about that content. They enforce MasterCard's rules with the bare minimum effort that their contract requires.
The best thing that could happen is another payment processor emerges that can compete with MasterCard's infrastructure, and doesn't have a board filled with bible thumpers. Since that's unlikely to happen, we should just be thankful that downloading and installing a patch, or manually choosing relationships, is a very simple thing to do. We should also be grateful that devs, and completely unrelated third parties are willing to put in the extra effort to bypass MasterCard's BS censorship.
