You're absolutely right. But it's sad that comments like this even need to be made. Like people constantly forget that usability is a thing and not everyone has infinite free time to burn on setting things up.
..especially for open source. Increasing the time barrier/complexity just to chat is a big turn off. I already use Slack for work, so adding FOSS projects would be easy. But if I have to fiddle with chat, that's time I could be coding or doing something more productive.
This whole discussion is similar to that Ogg vs MP3 file nonsense on Wikipedia; the victory of philosophical purity over practicality and usability. I still can't just click a Wikipedia sound file on my iPhone and have it just work. Victory for ideological purity big fail for the 98% of the world that doesn't give a s--t about file formats or Jimmy Wales's religion.
