I think you have a fundamental misunderstanding of how copyright works. Hint: It doesn't work much like you seem to think it does.TravisR said:It's easy. If you didn't make the work, you don't get to change it
http://en.wikipedia.org/wiki/CopyrightCopyright is a legal concept, enacted by most governments, giving the creator of an original work exclusive rights to it, usually for a limited time.
The Key phrase there is "For a limited time". If you never want your work to be modified you will have to keep it private. If you want to make a buck from it tho you'll have to live with it's limitations. those include some big ones.

The most misunderstood of those is Fair Use:

IANAL and you need to be to understand the nuances of Fair Use, take a look at that article and see what I mean.
But, there is nothing that prohibits anyone from taking copyrighted works and modifying it for your their consumption. Now if it leaks, then the sharks come out.
