Maybe, but Google, Microsoft, FB and other top tech companies are even more connected to colleges than NSA. They know their top students and can easily lure them with grants and even prizes. I remember talking to PHD students having to live on $20K a year, imagine how a $50K grant and a possible $1 Million prize feels to him /her. If needed, tech companies as a whole can very easily outspend NSA, if they want to. Unless they do something, other than filing PR lawsuits, they have only themselves to blame. (Of course the brightest mathematicians are used to fool people into clicking on ads. But that's another story.)
