LinkedIn may be less hypocritical than it first appears:

February 2022: LinkedIn sue Mantheos.

April 18, 2022: TechCrunch runs an article [0] stating that a U.S. appellate court affirms the legality of scraping publicly available data.

So IIUC, LinkedIn was consistently playing to the apparent law.

EDIT: oops, forgot the link!
