And I supposed to care that the poor SEO assholes that need to get their ads more visibility weren’t being given all the instructions on how to do that by the search engine?
No. You're supposed to care that a company is pointlessly* lying, thus it's extremely likely to deceive, mislead and lie when it gets some benefit out of it.
In other words: SEO arseholes can ligma, Google is lying to you and me too.
*I say "pointlessly" because not disclosing info would achieve practically the same result as lying.
