Patreon is fucked. The moment you take in investors, and especially VC investors. You are expected to give them a return on their investment.
This means that Patreon will have to get more people on board, they will have to make more money off everyone.
This is probably not great new. Either the creators have to eat the increased fees or the supporters; the former means less money for the creators and the latter means that a lot of people will drop off, and less money for everyone.
Also: remember that patreon bought memberful last year.
