Having gotten involved a bit over the last week, I think he's generally a good guy. I disagree with his politics, but none of that has anything to do with software development. He writes good code, and when he's not overwhelmed with nonsense, he's quite helpful.

There's another major dev, but I don't know anything about him. I think they just want to build a cool tool that they can use to provide a safe space for discussion, and they want to make that available to others as well. That's pretty cool, and that's something I can support.
