Sure they have pursued some questionable patent cases - but it is hard to deny they are one of the pre-eminent creators and makers in the world today - they have been truly innovative and brought massive change to multiple technology streams. They are about as far from being a hoarding patent troll as one could imagine yet that is how they seem to be portrayed in some parts of social media.
Even if you strongly disagree with their approach to suing competitors, I would have thought the real innovation and change Apple has brought to the scene would count for something and result in some more balanced coverage.
I think some of the specific patent cases Apple is pursuing against Samsung are a bit ridiculous (rounded corners), but I also think when you look at what Samsung has done as a whole, it is pretty clear they were ripping off Apple designs for a while (try and play spot the difference between a Apple 3GS and a Galaxy S1). Maybe Apple had to pursue the more silly specific patent cases because there was no way to patent the overall look-and-feel of a device (no lawyer here).
Anyway just my 2c
