I don't think the level of engagement is helpful, in the end it makes a terrible hodgepodge product that no one really wants, especially the dev who had an idea for a game that has been co-opted into something very different by their "customers".

I am not saying devs shouldn't get feedback, I just don't think they should be taking feedback from EVERYONE.

Personally if I ever wanted to release a game I would never have a public discord where people could contact me. Would I have a private discord where some other indie devs I know are invited for feedback and play testing? Absolutely. But, I wouldn't just let anyone in there.
