The problem with ditching services like Discord or Google Docs or Dropbox isn't me, I'm happy to do it. It's everyones I need to work with. They aren't going to join my self-hosted service just to exchange work files or chat, etc. I've tried.
Yeah, that sucks. I got away from most big tech stuff and other services/apps i consider immoral and/or unethical, but i can't leave, for example, WhatsApp, since doing that would cut me off from communicating with most of my country.
