I have a way to describe this. I call it "they need everybody yet they need nobody". They have decided that they would rather have contact from as many people as possible and be the filter that decides if what someone is offering (or wanting) is desirable to them or not. The other side of this is (back in the day) people who would do a version of "serious inquiries only" which would surely scare off all but the hardiest people.
