As a non-US citizen who just casually observes US news like an outsider, I can think of the below reasons:<p>1. The technology industry and EFF is very upset because of the ongoing patent-trolls issue. Only recently, a technoloy company was extracted of $625 million by the East Texas jury. Similarly, Oracle is trolling over its Java patent  on a matter as trivial as the Java API. These two incidents are enough for the technology community to lose faith in POTUS&#x2F;SCOTUS.<p>2. The second group which is not happy is the entire populace who like an open market and free competition. Power users who understand it know that Net-neutrality is harming it a lot. Again, POTUS&#x2F;SCOTUS is not listening to this problem, but has turned a blind eye to it.<p>As an outsider, my assessment could very well be observed, but I do think that these issues have enough potential to cause a feeling of anger and distrust in a lot of Americans (if not all). Ignorance or inactivity on part of POTUS&#x2F;SCOTUS is only going to aggravate it.
