I use one of these tokens for work. Spying is one thing but destroying encryption is another evil thing to do. If the NSA has introduced bugs in crypto then who's to say someone else can exploit the same crypto.
a nsa official just did an obvious trial-balloon of pardoning snowden in exchange for return of all the docs [1]
but now that snowden is in russia, you have to assume that many nation-states have seen all these docs. so really, the nsa is worried that you and I will see them
fucking amazing
