Google employees tens of thousands of people. The US intelligence apparatus employees hundreds of thousands of people. In all of that, over eight years, there are 251 people who moved between the two, and because of that absolute rounding error, the entire federal government is beholden to them?
Since you are making the accusation that this is a real conspiracy: statistically, how many people should have rotated between these two giant employers over an 8 year span? The answer isn't zero.
Also, this makes the "data" even more pointless:
"between Google or related firms, and the federal government, national political campaigns and Congress during President Obama’s time in office"
"were appointed to federal advisory boards."
Do you know how many of those boards exist? There are tons of them. I've known a couple of people who have served on them. They're incredibly boring and deal with things like "What accessibility standards should federal government websites support?". Of course you would want people from Google on that type of board.
> 251 individuals in such detected instances just in google. And that report is 10 years old, I'd bet it's 10x that by now.
"Detected instances"
It's so secret that I can name one of them off the top of my head: Matt Cutts. Is he part of this vast conspiracy too?
If you think it is "nice evidence", how many people should have moved between those two employers?
And you made the claim that the rate likely drastically increased over the past 10 years. Based on what, exactly?
