A few days back Google was displaying Featured Snippets with overlays, some of which were autogenerated web stories by Google’s own AI techniques. Google has categorized those stories under 404 and deleted them all. Almost 20,200 stories are deleted and 404 is displayed if they are checked in the search result. Soon they will be removed from the search results also.

I still see the contextual links but I have to click on the dotted word to have them overlay now. pic.twitter.com/IOZvB5GBgJ

It may be that this type of error will come again in which Google builds its own content based on others content and ranked the content over, however it was a quick action taken by Google. Currently, it has been deleted and 404ed.
