You've argued that legal protections, including China's stronger IP stance, means that USB-IF can be confident about cracking down on counterfeiting, and that it doesn't matter that the connector is east to reverse-engineer.

How does it help anti-counterfeiting and why are the legal mechanisms by themselves insufficient?
