Well, that presupposes that patreon itself is the publisher and you as patron/payee are doing business with them and not with the author. Which is the same model that youtube uses. I have never been author on patreon, so i have no idea about their setup. If this is the case then obviously that is perfectly legal. The problem then becomes censorship because patreon then is the owner of the license for your work that they are selling themselves and giving you your cut. Quite a different business model but one that "protects" the identity of the author because they are essentially sub-contracotrs.
