In any case. Countries where software is protected by patent might have isues with the illegality of software. I am happy Ecuador is covered only by copyright. I hope someday it won't be even covered by copyright.
Knowledge is universal and should be owned by nobody. If you don't want anybody to use it, then don't make it public. The moment you make it public you shouldn't restrict the use because someone might develop that same work without him knowing yours. It would be unfair for him/her. It would not be fair to repeat someone's words. If we would do as it is established in the law it could be applicable to that extent. NOT FAIR.
