I mean, of course there are people that say this ''same old, same old'' every week, but i can guess that there are also people that were a patreon once and decided to stop it(most of them have really low amount of posts), so this place is the only one where they can express their feelings without being silenced or something.
I don't remember ICSTOR being very active on social media and from i saw on patreon when someone is paying and criticizing something, then you have full band of fanboys that just can't take it, usually the same goes for discord that represents certain game.. Basically you can't say bad.
Not only pirates are here and let's be honest, dev communication usually sucks, so yeah i can understand the frustration from those and since he has so many patreons, i would bet that there's huge amount of people that visit this forum from that group.
