assuming Discord wouldn’t be replaced by something equally closed off from easy public access

That’s what I mean by issue of culture. I don’t think the habit of gathering on discord-like services to quickly exchange info will change, and if the explosion of bsky is anything to go by, people will just find the next shiny, pretty and well-funded platform that totally definitely won’t enshittify somewhere down the line to pay back their venture capital investors.

We’d be cutting the weed without pulling the root.
