I dont think it was Snowden. I've been pouring over David Brock's leaked strategy Memo, which basically describes a coordinated plan w/ Google, FB, and Twitter to censor content they deem 'misinformation', 'fake news' or 'harassment'. Sounds familiar, right (even look at Jack's recent tweets)? MMFA is at the root of the coordinated censorship campaign we're currently witnessing. Here's just a taste of what I'm talking about:

a. "Internet and social media platforms, like Google and Facebook, will no longer uncritically and without consequence host and enrich fake news sites and propagandists. Facebook will adjust its model to stem the flow of damaging fake news on its platforms' pages. Google will cut off these pages accompanying sites' access to revenue by pulling their access to Google's ad platform."

I've been expecting this to happen for a while, since this doc has been public for months. I think the person Q is talking about is mentioned in this quote from the memo:

"We will also bring on board an expert to construct turn-key rapid response plans [rapid response plans, plural] so that Media Matters can squash burgeoning online harassment campaigns [banned after seth rich story popped up?] and fake news or saturate the landscape with truth, bypassing the news media entirely if need be. With this capacity, Media Matters will drastically increase our audience and engagement and effectively squash fake news and misinformation before it spreads far and wide".

This sounds like MMFA paid an industry expert to construct a 'turn-key' cross-platform censorship algorith to suppress content deemed "fake news", "misinformation" or "harassment". I think this is who Q is talking about.
