Scapular retraction on bench press

I’m not exactly sure if this is the place to ask this, but when bench pressing, what are the recommendations for scapular retraction/depression? I’ve read things by coaches such as Paul Carter about how doing so can permanently damage the shoulders because it doesn’t let the scapula move around the rib cage like they’re supposed to, but the opposite by Dave Tate and the coaches at this website and such saying things such as doing so actually protects the shoulders. I know you teach retracting the scapula on bench press, but is there a certain amount, like, “some but not too much,” or is it more of an “all you can do” kind of thing? Also, what are your opinions on the opposing arguments listed above?

Thanks
