THIS is why I give my business to companies like NewEgg, and have and will NEVER buy a single damn thing from ones like Amazon.
Amazon settled because it is also a patent troll. Blood runs thicker than water, especially between patent trolls.
Amazon are not pure patent trolls or they would not have been sued. They actually use their technologies. I'm not saying they are squeaky clean, I certainly didn't like their 1 click patent, but they are not a complete troll.
Indeed, the genius of the pure patent troll company is that I can never be attacked in the same way it attacks. Since the troll company doesn't produce any useful products or services, there's no activity it does which could be considered for patent infringement, at least until one of them is granted a patent on enforcing patents as a business method.
Big corporations wield large portfolios of patents as weapons all the time, suing and countersuing each other when it looks like that action will help profits. While this is a very damaging abuse of the patent system, it's quite different from the type of trolling described in TFA. Also, the fact that Amazon chose to settle has little to do with how that company may have abused their patents in the past. They made a decision calculated to be best for their bottom line, whether that was a correct decision or not.
As a customer, I think it's a mistake to make broad buying decisions based solely on one aspect such as the suits described in TFA. I've been a customer of NewEgg for years because they have good prices and service and now I have yet another reason to use and recommend them. I've also been a customer of Amazon, especially of their music store which has long provided downloads unencumbered by DRM, proprietary formats or requirements to use specific client software. OTOH, I'd never use Amazon's Kindle system with its very restrictive DRM and other lock-in mechanisms.
