Don't confuse the idea with the application. Should the person who invented automatic door opening not get a patent because people already knew how to open a door?
I ma not defending the patent troll, but you reasoning is seriously flawed, and shows an almost complete ignorance of the patent system.
The difference is that is actually technology and an invention. It didn't exist until it was created. Even then someone could create something similar and patent it themselves. In this case, the patent was filed 5, 10, 15 years after it was being used in mainstream and they have no product.
