I think thats right and wrong.
You can dissasemble their program and write your own still..not using
any of their code and still not violate their copyright...
However...it is hard, if not impossible to prove that you didn't steal
This is where the "clean room" idea of reverse engineering comes in.
1 person reverse engineers the code and documents it. They would
extensivly document how the whole thing works. (without code)
Then hands the docs to a second party who then codes it.
In this manner the coder has not even seen the copyrighted work and
thus can not possibly copy it
