I am guessing all of the above. Blaming the White House probably depends on how you feel about Obama to start with. I can imagine some of his supporters have to feel disappointed that this has not only continued in his Administration, but has also probably expanded since Bush left office.
IMO, the buck for this sort of thing stops with the President. He either had to authorize this or the top people which would be appointed by him had to okay it.
Overall though, you see mixed opinions. Some are fine with this stuff because it "makes us safer", some are appalled that we are spying on our own people and our Allies, and a decent portion are upset the Lamar Odom and whatever Kardashian he is married to might be splitting up.
Obama's numbers amongst younger voters have taken a dive lately and most think it is tied to this sort of thing, so he is paying a price and he has not really made a case for why this should go on. I know he said something about a mixture between liberties and security is needed .. but that was when this first broke, there have been many revelations since then and he has not really responded to them.
