Well, yes and no.
Theo's absolutism has kept OpenBSD pretty much the last
blob-free OS in the Free Software world.
RMS's absolutism has kept alive an ideal that launched
the mainstream open source movement.
So it's not non-functional. It's emotionally hard on the
individuals concerned, and often emotionally hard on
us who bask in the reflected glow of these geniuses :-).
But it all seems to work out in practice. Has for a cuple
of decades now, give or take a few years.
