Fine, the copyright protection for Google's algorithm has evaporated. Where do you plan on getting a copy of it? And even if you did somehow acquire it, how do you plan on using it without violating Google's trade secret protection on it?
There are existing legal frameworks in place (trade secret, trademark, service marks, etc.) that complement copyright and would enable software (and movies!) to remain viable enterprises even with drastically shorter copyright terms (or no copyright at all.)
