Hmm.. not me, not so much. I think usually when a ball gets to the plate early enough, and a collision is coming, that a catcher can quick drop into a solid defensive posture and protect himself, and as long as he holds the ball the ump should give him the benefit of the doubt. But on those closer plays the catcher is still in motion fielding the ball or whatever, and not prepared to take that hit, which was the case in the Buster Posey play. (which should have been a swipe slide). The home plate collision is very much a desperation and instinct move on the runners part, who usually knows he's going to be out unless he can jar the ball free. To this point collisions have been "part of the game" which is what most players will say in an interview afterward. If MLB wants to reduce their occurrences to near zero, then hopefully they will present some specific rules and suggestions, instead of just agreeing to some vague "ban" against it. And you will still see foul tips and collisions between teammates in the field, so yeah.
