The whole patreon crackdown i can imagine has hit alot of games hard.
Though if i were to give a probable reason, for patreon´s actions, i would say that it has probably something to do with the abolishment of the safe haven for most services.
Before the individual services couldn´t be held accountable for their user actions, meaning if somebody used Patreon or some other services to perform illegal acts, well it would be the one who performed those acts who would be held accountable.
The service itself could not be held accountable for their users actions, they just provided a service and that was that.
Now with more and more countries abolishing the safe haven for various companies, they CAN be held accountable for the actions of their users.
So in order to avoid a shitstorm Patreon did what they did.
That´s the only explanation i can give that defends patreon´s actions.
All other explanations doesn´t speak well of either Patreon or silicon valley.
Basically if youtubers like The Quartering, Sargon of Akkad and Computing forever, is to be believed, both patreon and silicon valley has been infiltrated by extreme leftist moral busybodies, who cracks down on anything they deem offensive and removes it, this includes people leveling critique against them.
And one of the things hit it the crossfire is games like this.
Though i can´t help but wonder, i have heard of other services like makers support or hatreon, where the rules should be more relaxed, so maybe switch to one of those and get the money to continue making the games we all like to see ?
