I disagree, if the thread is properly tagged (with a "planned tags section) there's no reason to discuss fetishes at all.The thread can be derailed in several way, discussing fetish is usually guilty of that (eg. ntr brigade), but I don't think they should make a rule so peoples are not allowed to talk about fetish in the game's thread.
It's also full of people that ask questions that have been answered a post or two above their own. How to use the search bar seems like esoteric knowledge sometimes.What this place has that discord and patreon (and any other more secluded area of conversation) doesn't is that it's full of different peoples, asking about an opinion on patreon is like asking peoples coming out of bakery if they like bread.
I think there's a bit of a difference between not being antagonistic to the devs vision, and thinking it can be improved. Most discords I know have specific channels for suggestions and such. What discord can do is make it easier for a back and forth, discussing the suggestions and ironing things out much more smoothly. Here, conversations are a bit harder to have. They don't go as quickly or smoothly. Just the nature of a forum vs a dedicated chat app.If they are on theses platform it's certainly not because they are antagonist to the dev's vision.
Also to note, not everyone in my discord agrees with my decisions. There are actually quite a number of them that have expressed disappointment on the direction I've chosen for certain things. Anecdotal, but not every discord is just an echo chamber.
