And how do you defend hiding the repair schematics?

I mean if you fear someone would steal your IP then they can buy your product and scan it and they also can get the schematics from an employee from your authorized repair shop. For me is obvious that "We don't want to give the repair schematics and we will go after you for using or sharing them" is not to prevent some company stealing your IP but screwing with the repair shops even if we know that eventually you will get around this
