So rule changes are now advantage/disadvantage rather than player safety issues? Hand checking wasn't a foul before; it became one when the powers that be decided it was better for the game. Backing a player down from the three-point line was completely OK, until someone found a way to create an insurmountable advantage out of it. Hell, a good drop step is physical contact that creates an advantage; if Andre Drummond perfects an unstoppable drop step, should that suddenly become a foul too?
Face it--rules change when the governing body decides it's better for the product. I get that you're a hoops conservative, but maybe you should try to think more progressively.
