Fuck Patreon, people shouldn't pay anything to those censoring control freaks.
The problem is, they've become the de facto funding service. While alternatives like SubscribeStar exist, their userbase and profile is much smaller, meaning if you use them, you're dramatically limiting your own potential earnings. For creators who are trying to make a living via game dev, it can be the choice between whether or not you can successfully finish a product versus having to quit and get a "real job" to make ends meet.
So you get into that Catch-22 spiral, where in order to grow a service you need people to use it, but people can't/don't want to use it until you grow it. So the primary service remains primary (and can get away with whatever bullshit they want because they're functionally a monopoly), and none of the alternatives can really grow to the point of meaningfully challenging that position.
It's the same thing that keeps YouTube king in spite of all the myriad bullshit they pull (and they're currently in yet another phase of strangling the life out of smaller creators monetarily). Any alternative video hosting service is going to by definition be far worse for actually getting eyes on your video.
It sucks, but there aren't really a ton of options to change the way things are (at least none that are likely to actually work).
