The parent said "meant for communities" and not "used for communities".
The biggest difference I see is that Discord is "free" for communities, or at least the model is different: an individual user can apparently pay to contribute to the server and "unlock" features. Also I think Discord just comes with history for free, which is a killer feature in many communities.
Slack is more "meant for companies" in the sense that the "owner" of the server (i.e. the company) has to pay each month for each user. Many open source communities can't afford that, which is why they like the Discord model better.
Disclaimer: I hate both, because they don't have an open API and the Desktop apps use ElectronJS. So I'm not sure if I'm biased towards one or the other :D
I don't think it's the same. Maybe "is meant for" is not the right wording, but the point is really that the model of Discord just works better for communities, because the server admin does not have to pay for the users (rather the users can contribute to the server).
