While I think this is extremely hyperbolic, yeah the author isn't wrong. Discord is, for all intents and purposes, a privately owned public space. What you say and do there is public, is publically viewable effectively, and that extends to DMs. Likewise, Discord wants to maintain their public space with their rules. I disagree with these rules, but Discord is free to moderate their space as they see fit. Just like the owner of a private campground can kick you out for cursing, despite using curse words not being a crime, so can Discord ban you for posting nipples or cheat software. I think the only malfeasance here is that Discord looks and feels like a private space. It feels like a space where you can talk privately or share things privately, and so people are upset when that expectation turns out to be wrong. For some FOSS projects, I think Discord is a fine choice. It's low friction and it works well. I use it for my social groups. For many projects that might touch on software or topics that Discord dislikes, or that strongly disagree with Discords moderation, they should use an alternative (whether that's still public like IRC or potentially private like Riot)
