Stallman is said to be notoriously difficult to work with, and IMHO he's quite an extremist.
He tried to veto emoji support in Emacs, because at the time it's only been supported on macOS. The reasonable recourse would've been add emoji support on the free platforms, but he seemingly can't see that far. So he's been ousted from the project.
In situations like this, I honestly would prefer to shut him off as well. I have huge respect for his past work, but at this point he's doing more harm than good.
