Agreed, and that part (regarding ratting on the cops) is a bad argument. In any public chat, anyone can log. People log in IRC as well. As can servers. E2E encryption makes little sense there. If you do FOSS development, you might actually prefer to know the realnames of the people you develop with. You might want to (temporary) log chats between developers, to read them later. Surely, Mattermost and Discourse allow this as well. Also, Slack is barely mentioned in the article, while I'd say the same argument counts for Slack (but perhaps worse). The alternatives (Discourse, Mattermost, and Mumble), are three, which all 3 would replace Discord. But not on their own...
