It's possible gmaxwell has had enough abuse. Apparently he gave up commit access to the bitcoin github. I saw his last post was in this thread a few days ago.
I've found the abuse the Core devs and BlockStream to terrible. I wouldn't blame any of them for choosing to walk away. On certain (unimportant) forums there's some celebration of the idea that gmaxwell may be walking away. Reading it, I have to say that I would walk away from a community with so many evil people. Frankly, I don't want to be in a "community" with people like that either. If there were a way to boot all of them out and keep gmaxwell, I'd prefer that. If they'd just fork off and leave the rest of us with Bitcoin, things would probably be fine (after a shaking out period). Instead they seem intent on "occupying" Bitcoin.
I'm sure gmaxwell knows he has a lot of supporters in the Bitcoin community. That wouldn't change if he decided to leave. I think most people would understand.
It can be said that the other side feels this way as well. They might even say the same thing about their ideological opponents. Considering that many people did sign up for the vision of Satoshi which Core presently seems to be diverting from.
If Satoshi's vision was so well represented in the XT fork then maybe you can explain why it was unanimously rejected by Bitcoin users by and large?
