Facebook is under a criminal investigation for the reason of data sharing with tech firms. The criminal investigation is led by federal prosecutors who are seen examining data-sharing deals with other major technology companies.
Facebook seemed to be under fire since Cambridge Analytica revelations placed spotlight with concerns relating to the company's data and privacy practices. It was also sued by Washington DC in the month of late December for this purpose.
Facebook was also found giving companies, like Netflix, Spotify, Microsoft, Sony and Amazon, the ability to access user data with majority of third-parties.
