Ah, the post I responded to wasn't talking about Kovid's interactions with users.
I agree that he could do a lot better with controlling his emotions. Me and him are on the opposite ends of the tmux debate for example. But I understand his point, he's trying to solve the same problems that tmux solves, with a very different way.
The problem is that Kitty isn't there yet (I wish it was) and his outburst on the topic are quite damaging to his goals.
When you've met and worked with people in real live that are like that, you can just visualize them and have a laugh at their outbursts.
I'm still team Calibre and Kitty any day and tremendously thankful for what he's doing.
