Look at the use cases. Discord is very much known for people talking about video games , not much else.

Slack started as an internal business tool and it remains so.

There's a bunch of open source projects using it now as well. I have two separate family Discord servers. Quite a few social ones that aren't specifically gaming focused too.

Discord also caters to small-med non-gaming online communities almost by accident because the kinds of moderation features you'd need are the same as if you were a streamer with an audience.
