The Discord chat room is very little different from the (RIP) freenode channel. Sure, you need to create an account, but that's where communities are built nowadays - in closed groups that can be controlled, moderated properly, and automated, while still being a fun and friendly environment to chat in. It does that well.

Github is not open. All the things listed there are costly, in one way or another. There's nothing free about anything that makes up open source today. Open source became corporate some time in the late 00s. And while I don't agree with the author (including the fact that he calls the new product Ruby-powered, not Impaired by Ruby), I do agree with that strange assessment that open source communities work that way.

You can read Github without creating an account. You can't do that with Discord and it's becoming harder with Twitter. Discourse forums can be read without an account too. I agree that we should be careful of Github too.
