Personally I think that he owes them nothing, especially after the way he was treated in https://github.com/microsoft/terminal/issues/10362 so I can't comprehend statements which claim that he was an asshole for using GPL.
I'm saying he could have helped the situation, and he deliberately chose to not only avoid helping, but to hinder anyone at Microsoft who wanted to look at that code and contribute to Windows Terminal. That was a choice he made intentionally.
He could have taken the high road, there. He chose not to. It's his choice, don't get me wrong, he was well within his rights. I just disagree with that choice. that's why I call that a "dick move". And if you disagree with me, that's fine. "Dick move" means different things to different people at different times.
