I agree that Discord and Slack has some bad sides, but for kinda opposite reasons than the author. There are so many discussions, QAs, tips&tricks etc. shared on these chat rooms, that are impossible to find for those not a part of it. If it was discussed in a public forum somewhere, it would pop up in a search engine. I may have a problem with tool X and google for a solution, but since the discussion happened in some closed Discord server I will never find the solution someone else there has posted. So kinda the opposite of the author's point about privacy: I prefer everything to be open and accessible. Hiding this stuff hampers the adoption without people realizing. I don't join a discord for everything I use, and often I'm not even aware that it exists. An example I had a few weeks ago: Elm package repo died so I got some weird errors when building my project. Apparently lots of people were aware and knew about the problem and the status. But it was discussed in some Elm slack (I think), so for me not a member there I had no idea what was going on and couldn't find anything about it.
