Three large tax prep firms sent “extraordinarily sensitive” information on tens of millions of taxpayers to Facebook parent company Meta over the course of at least two years.
- They say some of that data was then used by Meta to create targeted advertising to its own users, other companies, and to train Meta’s algorithms.
- The firms in question are H&R Block, TaxAct and TaxSlayer shared with the social media giant, according to a report by congressional Democrats.
