I don't agree with this sentiment in its entirety, but I do agree with the frustration you have with its result. I personally believe that if there are products and brands that you like, there's nothing wrong with supporting that brand. I agree that there's loyalty and blind loyalty, but I think this has a lot more to do with emotions.

I think most people's emotions are about the actual point of patents. Patents were designed not to protect giant megacorporations like Apple, but to protect the little guy, the idea man. I talked with a lawyer on a plane recently about his cases involving Home Depot blatantly ripping off someone's idea for a product and paying them nothing.

So, the idea of someone defending their invention is a david vs. golliath sort of emotional situation, and people who are brand loyal to Apple want to see the "little guy" (yeah right) win in the end. But neither one of these guys are little, so I think this emotion is misplaced.
As an Open Source developer, I have to say that while Open Source is wholly built from the ground up new, many open source products are built from the ground up to be a very close copy of something outrageously expensive or simply proprietary and unavailable to the general public. To the Android fans, I think this must feel more like the SCO vs. Linux trials problems of the late 2000's. Who was the bad guy to me? SCO. Because to me, their claim of ownership was bogus and I am a Linux dork. SCO is the evil giant megacorporation trying to "take down" my open source heroes. What *******s.

But, here we are again with misplaced emotions. In that case, SCOs claim to copyright was indeed bogus. Furthermore, Google and Samsung are just as much a Megacorporation as Apple. Where's the little guy being protected or the revolutionaries fighting the man? Neither really exist.

I don't buy all of Apples claims of copying and I don't think patents are being used properly. But I equally don't buy these nonsense arguments that "there's only so many ways to make a tablet / OS" or "those two products look nothing alike".
