Cut the plug of and rewire it?
Yeah, I can do that, but then what am I giving them any money for in the first place?
The live and neutral are both safely terminated inside the PSU’s, so you can’t accidentally touch live.
Depends also on how surge / overvoltage protections operate, they might throw open the neutral line and leave live connected to the device... so yes it would break a circuit, but it would leave the device hot.
