Because of course it's impossible to change your release without one of those. Get real.
(And where'd he find one for $50? Mine cost $70)
If my ball's hooking too early, I adjust my release itself, not my wrist brace settings, to create more axis rotation for extra skid through the front part of the lane. Or, if I am so inclined, I can change balls to something weaker that gives me better length. I'm guessing that's something else that should be banned, right? Because then it's "all in the ball." Your logic is just as faulty as someone who would say that wrist braces have no effect whatsoever.
