the real problem with discord that makes them truly evil is that they sell their solution as being something that provides self-determination.
when you move your community to discord, you start a what they call a "discord server."
to be clear, there is not really any such thing as a "discord server," this is just marketing terminology for group functionality.
they call it a discord "server" on purpose: they want to communicate the idea that you have full autonomy on your own "discord server," when in reality you are still at the mercy of discord as a service provider. this is truly evil, this goes beyond a lack of transparency to actively lying to potential users. not even Slack does this.
we must build real alternatives to these predatory services.
