I can tell that some people want to stay away from Discord just because it’s been known to be a community for “gamers” and that you can’t do anything else serious with it.
I actually started a poll on twitter about this just before you guys made this announcement. I wanted to check if people avoid using OSS if they have a Discord community. Maybe it will be useful to see the votes: https://twitter.com/razvanilin/status/1373970324186824708
