Underlying it all, though, was that vim has a bus factor of 1: Bram. Bram is the sole chokepoint through which all change flows, and thus holds back a lot of community dev. Neovim early on pursued a working model allowing for a larger community of interested devs to contribute, and it's paid off: the originator of neovim has moved on and a new steward has taken over smoothly, and they have around 30 core contributors.
So your anger at Neovim is misplaced. They created a modern vim open to many devs, and incidentally rekindled active work on vim, which had been stagnant before. You should be thanking them, even if you don't switch. You have async and terminals in vim because of them.
