The parent article links to Assange's comments after meeting with Schmidt "Google is Not What it Seems" [1] which has some interesting discussion of the links between Google's senior level and politicians. Published yesterday, I don't recall seeing it linked.
You don't have to depend on an article to provide evidence of a connection between Google's execs and the political leadership.
The fact that those execs were getting cheap gas for their private jets is more than enough for anybody to put 2 and 2 together and get the right result.
