The limiting of copyright and patent is supported by advocates of such limitations on the basis of benefits from the work accruing in a more fair balance between the individual and society. It is stated on this thread and many others that it is society that chooses to allow patent and copyright to exist exactly in order to bring forth the work of individuals. The good of society is placed above that of the creator of the work.

If one likes that idea, it works even better in the case of 'trade secrets'. Abolishing trade secrets and instead substituting a time limit like that of a patent would REALLY let those benefits flow to society at large. We force pharmaceutical firms to come up with new ideas every patent cycle; why should software - after all, it's 'eating the world' and is a highly-maleable product - be exempt from that process of creative renewal?

Case in point: Microsoft used it's dominance gained from Windows to directly stifle competition, to the point where the law had to get involved.

Google was a disruptive force initially, but now they have begun to tweak their algorithm to fortify the walled-garden they wish to build - while also using the Microsoft model of buying up potentially disruptive companies.
