Help me understand - you are mad at the victim? Do you stop talking to friends because they paid for Windows? Don't buy anything with a Samsung-made component?
I'm sure Nikon looked at the cost of fighting and decided it made business sense to pay them. Consider the volume of Android devices Nikon sells vs. Samsung and other cell phone companies. If it doesn't make sense for the cell phone vendors, it is unlikely to make sense for Nikon to fight in court.
Frankly, your anger toward Microsoft might be better directed at Microsoft. And Google. Why hasn't Google challenged this?
I will not be purchasing Nikon products because I want other companies to understand the full price of caving in to patent trolls. I will pay a little more to support a company with a spine and a long term outlook on the situation. Unfortunately it is getting harder and harder to find such companies.
