The change from pay per episode to per month was a direct result of crApple’s 30% tax. This hurt Patreon directly because a bunch of creators were pissed about the change and blamed Patreon for not fighting back, so they left. So Patreon has lost revenue over this, how much I have no idea but I know several of the podcasts I listen to have stopped asking you to pay via Patreon and are now asking you to donate via Substack or their private donation page.
