To me, it's obvious that core developers have lost the plot on what bitcoin is for, money. And I hear very little constructive conversation on the issue. And I think it matters a lot. I hear people on core calling the knots supporters stupid with no real reasoning. I am not usually called stupid. This is new to me.
Discussion
I've seen this behavior on a personal scale at work. Someone gets contacted to work on a project, they are used to people just doing what they are told and having things go their way. Then people don't agree with them and decide to go a different direction from their "suggestions" and there's a falling out that gets taken personally because they don't know how to handle the dissention.
There's definitely more to it than that, but this reminds me of such experiences.
