I get this is the go-to response now, for good reason, but there isn't really anything too shady going on with this particular case at least not from Google. This is more about them trying to keep SEOs from figuring out how they rank things so they can't pollute the search results even more.

Every comment is shitting on Google but here is the what the SEO expert said about the leak when it was presented to them:

This person’s sole aim appeared quite aligned with my own: to hold Google accountable for public statements that conflict with private conversations and leaked documentation, and to bring greater transparency to the field of search marketing. And they believed that, despite my years removed from SEO, I was the best person to share this publicly.

Just read through that blog. Look at the absolute indignity these SEO assholes have at the idea that the search engine wouldn't tell them exactly how to fuck it up with their garbage.

This is entirely about advertising. Hell, the leaker revealed their identity, and it's the guy that runs this company:

Companies like this and the assholes behind them are a cancer on the internet and they have been for a very long time. You cannot point the finger at Google and not also point the finger at them, they are the other half of the shit equation.

Forgive me for not reading all 2500 documents, but I haven't heard anything to suggest there was a bunch of sinister stuff in there -- and there's nothing implicitly evil about having docs leaked.
