Meta is being sued for giving US hospitals a data-tracking tool that allegedly ended up disclosing patient information to Facebook

A new lawsuit alleges that Meta has access to the private medical data of millions of people without permission and has used it to serve targeted medicine and treatment ads on Facebook. 

The suit, which was filed last week in the Northern District of California, is the second such lawsuit that accuses US hospitals of providing Meta with sensitive patient information and violating HIPAA. The Verge originally reported on the suit earlier Tuesday.
