However, talking of software, although copyright expires, you will never know
what software did and does, since there is no law that says that the source
code must be showed when copyright expires. It is big deal since lets
software writers to release malevolent programs.
At any case, thinking on reusing the code, it is not important that source
code is not available after finish copyright because software changes very
very fast: ¡only 5 years is a lot! That code would be only interesting for
didactic or recreational purposes after expiration of copyright.
What free software reclaims is that source code and the possibility of modify
it is available from the first moment that anyone can run it!
