I see it as: there's a finite amount of people who choose to dedicate their unpaid free time contributing to making Rust better (working on fixing bugs, new features, etc.)
This seems like fragmentation which basically will slow down progress. Now, obviously the people who choose to dedicate their free time to open source software are entitled to do whatever they want with it. I don't know the details of what part of what leadership is doing what that equates to "being a meanie" and I don't know who is "being dramatic" and who isn't.
All I know is, I'm grateful for their contributions and wish everybody could get along. This is kind of "not a good thing" for progress when you look at it from a delivery perspective.
