BS. And based on what exactly? Reputation?

Your view, but in my time here that has not been the case. I can count on one hand the number of aircraft refusals which have occurred on my trips, and that's not using my thumb.

Unless you are talking about LCAL guys. I have next to zero experience with them. I have only flown with one LCAL Captain and he was top-notch and an excellent guy to work with.
