I understand he’s mad that he’s losing money of a thing he made but, I think he’s going about that the wrong way. I would see that as more of a challenge then a “wow I shouldn’t do this”, I expect any person doing stuff like this would look at it the same way, free cracks and exploits are rarely about the money, it’s generally about the challenge of doing something that isn’t supposed to be allowed. Adding “mines” to try and sabotage it I believe will just make someone more apt to try and crack it.
