Momentum.
The average person is really hard to move to a new platform. I saw this when Skype was the big thing for internet communication the Microsoft slowly made it worse and worse before it was barely a shadow of its former self.
Alternatives existed, many that were much better, but they were slightly harder to use or came along way after people were already set on Skype.
It wasn’t until discord that the internet shifted, but even discord has its problems.
Kind of what the whole thing in civil war was. Tony was looking to absolve his guilt over the people they failed to save while looking for more and more authoritarian methods of keeping the world “safe”.
Cap was much more for freedom and while the idea that the avengers should have absolutely no oversight is absurd, the question of who should be the oversight was important and much of what the avengers did could not wait on a committee to decide to act (also, the last time a committee did act they decided to nuke New York)
I’m ADHD and probably on the spectrum. Most of my friends are some level of both too.
There are still assholes who are also neurodivergent. I’ve met some. I avoid them. I will generally get along with other neurospicy people, especially if their combination is closer to my own, but an asshole is still an asshole.
