Code protecting microcontrollers, even if not 100% secure, is effective on a non-technical basis. You are showing due diligence by "protecting your intellectual property". It doesn't need to be perfect, just like software copy protection methods are not perfect yet still continue to be used. Thankfully microcontroller protection doesn't have the side-effects to the user that software copy protection often has.
