There are loopholes. For instance, if instead of spying on the people you pay someone else to do it and become a "Witness" or to come forward with evidence then it is above board. For instance, if Facebook were to sell your info to the FBI and then they used it against you in a case then it is totally above board.
It's kind of like how if you watch your neighbor murder a poodle and you call the cops, they don't need to get a warrant if you want to testify.
In this case, the witness was a person agreeing to a reduced sentence in exchange for developing ANOM.
