It isn't always as egregious as the eBay case. SLAPPs (https://en.wikipedia.org/wiki/Strategic_lawsuit_against_publ...) are one example. Then there are Twitter-fests such as Arizona Public Service (https://azcapitoltimes.com/news/2019/07/30/aps-allies-attack...), involvement in political campaigns against elected critics (https://www.nytimes.com/2020/05/03/technology/amazon-pramila...).

On the other hand, there's the Kerr-McGee corporation (https://en.wikipedia.org/wiki/Karen_Silkwood), Monsanto (https://www.theguardian.com/business/2019/aug/07/monsanto-fu...), and Bloomberg LP (https://www.npr.org/2020/04/14/828565428/bloomberg-news-kill...).

Corporate investigations is an industry, too. (https://www.aegis.com/investigations/corporate-investigation...)

Them getting caught required a bit of extraordinary luck on the part of the victims and a lot of over-confidence on the part of the perps.

After almost getting spotted once they came back and the victims managed to get a photo of their tag.

Without that the whole thing would probably be dismissed by people as a crazy conspiracy theory.
