This is just my opinion. I do not think any body will buy x-ray machine to erase any otp's. ( sounds like no thing to do ) engineers or hackers just wants to more about PIC MCUs or they like it a lot wants to learn more about it. what are they going to do with it I do not know. this is what I know if Microchip found that OTP's are enable by x-ray they will come up a solution right a way you do not even notice it.
