I see the same engagement issues everywhere on the internet, including this site where discussions constantly veer off into the same old fights. I realize it's tempting to focus more blame and hate on facebook (I don't like it either, and Zuckerberg especially seems like a first-rate snake). But this idea that they "infect people with mind-viruses", or whatever, is just too reductionist and misses how they actually operate, which is simply "fill a need people have so those people will use the product and you can sell ads". It just happens to be a baser need we'd rather people not go fill. I have read that in the past everyone just drank alcohol constantly to escape, so maybe it's progress.
As for this person's specific complaint of hypocrisy or whatever, I don't actually think the imposition of "silicon valley values" or whatever into their operation is at all beneficial to IT companies' finances. I'd place it under the category of hackers, who are abusing/corrupting the automated moderation systems and forcing the company to waste money trying to actually be fair and not alienate half their potential customers, not earn more money by it.
