You appear far less objective than GScholz to be honest.
The wikileaks files include stuff from Snowden and Manning. Manning is in jail (
https://en.wikipedia.org/wiki/United_States_v._Manning ). Snowden is wanted by the USA for espionage (
https://en.wikipedia.org/wiki/Edward_Snowden ) and is currently in hiding in Russia.
Julian Assange (who ran wikileaks) is currently wanted by the US and living under asylum at the Ecuadorian embassy in London (
https://en.wikipedia.org/wiki/Julian_Assange ).
The format of the NSA Slides is quite common, if you look at any of them they look the same.
In NZ we had great interest in them as we are part of the 5 Eyes/Echelon program.
Nobody (except GS) has ever disputed the validity of the wikileaks NSA files.
Snowdens leaks in particular created a massive upheaval in the IT industry around encryption of data after it revealed what the NSA was doing across datacenters such as googles.
ALL the NSA slides bare the same format.
Denial of these slides as 'conspiracy theory' reveals someone who has no clue / is very ignorant on the subject.
I would suggest gs read up on snowden and manning more. But I doubt he will.
