A company is not a "patent troll" unless the company makes a living only doing it. However, what Apple brought against Samsung and what is being described here is a pretty clear-cut case of patent trolling.
I don't think you know what patent trolling means, neither how patents work.
They patented "the ornamental design for an electronic device" which is a "thin rectangular cuboid with rounded corners"[2]. Tell me with a straight face this is the point of the patent system.

You do not understand the term "patent trolling". Give up.
