Luckily, there are Discord alternatives that exist. A lot of them actually, I think a lot of them are open sourced. I know there's Matrix and Revolt (I quite like Revolt a lot, so I hope that goes somewhere). They do lack some things (I think screensharing being the biggest?) but they capture the essence of discord. Will they take off hard? Who knows. I'd like Revolt to a lot, it just feels nice to use.
