On 8chan qresearch they say fiddler is Snowdon.
whenever I hear the term “Fiddler” then I think of a very memorable character from the TV series called “Roots”.
Fiddler pretended to be totally in with his white masters while behind the scenes he was working against them. If I remember correctly he actually put on a special performance in order to distract his masters while a slave was escaping.
So my interpretation of “Fiddler” is someone who is putting on a show, and pretending to be someone they are not.
So it could very well refer to Edward Snowden.
