Uh, what? Do you really think Google's special results at the top are "organic"? Of course they aren't, they are trying to put the most useful information at the top of the page. No conspiracy there...
I noticed in all the posted screenshots that while Google does link to itself from time to time, it also links to alternatives. In the health example, it linked to Google Health, but also the Mayo Clinic and WebMD. This is just an example of Google trying to provide the most useful answer to the question you typed in. Not a conspiracy :)
Flagged for senseless Google hate.
