In fact, there is no clear indication that they did not act in what they perceived as the interest of the US and its citizens. Many would disagree with that perception, and I also believe that amount of surveillance to have been wrong and counterproductive, but there hasn't been any evidence or significant hints into possible corrupt motivations. One mustn't forget that all of this was put into motion after the 9/11 attacks, and both the Bush and Obama administrations where still working under (somewhat irrational) pressure from citizens afraid of a repeat performance.
