It's one of the best article about this issue I have ever read!

Almost everything that needs to be said is there. I am always wondering why people are constantly confusing copyright/intellectual property and (software) patents...
If you
grant a software patent (at least in 99,99999...% of the cases) you basically allow the patent holder to do exactly the same thing that copyrights are
trying to prevent: To benefit from someone elses work without having anything contributed (this is theft, in my opinion). Someone does the work and you get the money... isn't this the same that happens if you breach the copyright??
One of Amazon's arguments for their patent of the "One click oder" was the effort to develop this feature for their portal. And this is wrong, since a patent isn't meant to cover the costs they had to
implement their idea (which is certainly not an invention either).
