Ive been through Snowdens leaks at length. Alot of interesting stuff in there. If he only hadn't given the gchq info to pussies… He has info on quantum hacking, quantum entanglement communication by UK and Sweden, and a number of other interesting things in there. You can likely still find on torrent sites.
Q's reference was just trying to get u to picture the style/scale by comparing to xkeyscore. Don't mk huge thing of it. You'll get lost in the weeds. Yeah it's bs but alot more to dig into blv me.
