Similar history and similar peeve here. It's much the same as many other fields though -- the people who think loudspeaker cable is directional, and so on.

There is some hope -- if you look for interviews with Billy Gibbons' "tech" guy he talks about how they ran his favorite guitar (Pearly Gates) through a SA while playing an open G cord. Then for every other guitar he plays live they program an EQ spectrum to bring it to the same spectrum as that baseline guitar. So they all sound the same (because it's only EQ that differs between pickups not 1960s magic smoke).
