So by now most people have probably read the New York Times deep dive into what can only be described as Facebook's deep well of internal dysfunction and self delusion. While there's a lot of interesting bits in the piece, one portion that received some extra, justified hyperventilation was the revelation of Facebook's use of smear merchants. Smear merchants that the Times notes Facebook employed to try and discredit those pointing out that Facebook's privacy practices have generally been hot garbage:

"While Mr. Zuckerberg has conducted a public apology tour in the last year, Ms. Sandberg has overseen an aggressive lobbying campaign to combat Facebook’s critics, shift public anger toward rival companies and ward off damaging regulation. Facebook employed a Republican opposition-research firm to discredit activist protesters, in part by linking them to the liberal financier George Soros. It also tapped its business relationships, lobbying a Jewish civil rights group to cast some criticism of the company as anti-Semitic."
