Snowden being MI6 is the wrong track.
Snowden was working with Schmidt/Google. Snowden wrote the censorship code which ties into Twitter/@jack. We know that both twitter and google are used by the CIA. Nothing Q has told us or that we have researched connects all those together except the CIA.
Snowden>Google>C-link>Private Google servers overseas>CIA>Social Media>NK>China>China made electronics/tech/products being regulated
These all tie together. Has nothing to do with MI6.
