The earliest notable one I can think of is the whole Kellogs and Breitbart incident. However, specifically relating to Google, I'd say it's the James Damore political silencing by Google. And even more recently, Youtube has started censoring controversial videos and putting them inside a "gimped" version of Youtube. I.e. no likes/shares/related videos. It really is turning into a 1984 scenario.

1984, where the government literally rewrites books, changes the language to be incapable of expressing dissent, and murders its citizens.

Comparable to firing a guy who upset a huge portion of the company and false positives on hate detection algorithms. Sure.

Yes, no likes/shares/related, but on top of that, the videos are demonetized + no longer embeddable.
