I think the problem is guys who DON'T know any better tend to think only flat barbell bench is the way to go, so the others who don't know any better follow suit, but I like to mix it up with dumbbells, I'll do pull overs superset with my bench at times, HELL I've deadlifted superset with my flat bench, but I'll stay light on bench only 225, and go up to 405 on deads.
