I think you are right about that. It's a tricky one for me, as the pedant in me wants to argue for the singular thing, but the reasonable voice in me says, "Um, dude, it's pretty much always been that way. Let it go. You sound ridonk saying 'his or her' anyway."

Continue fighting for "fewer," please! I, too, have been correcting egregious errors against it for some time.
