There are regular comments by declared employees of quite a few companies including Google on HN. The commenting and vote/flag brigadeering around subjects that center on one of these companies is such that many subjects are either voted off the homepage entirely or the participants in the thread get downvoted/upvoted to better support the company position or narrative.
Whatever else it is, it's one of the more important guidelines of the site (at least judging from the time Dan and Scott spend on it) that you not make appeals like this in public comment threads. What evidence you hsve of this, you should send to hn@yc.
How is that evidence of "vote/flag brigadeering around subjects that center on one of these companies [...]" by those people? This story sat on the front page for a day, has zillions of votes and comments and as far as I can tell, even people who work in the field can't actually figure out what it's about.
This is all quite in the open.
