Thanks for pointing this out. I've brought this up many times, but people seem to gloss over it. These more recent programs simply remove red tape. This has been going on at least since the Regan administration(perhaps before with Carter). While it may be "illegal" to spy on your citizens, there's nothing against spying on your ally's populace and then having them reciprocate the favor. Share intelligence reports and you are now successful in spying on the entire world.
