Just days after the DOJ filed an antitrust case against Google, the FTC may be planning a similar case against Facebook.

Tech giants are under more scrutiny now than at any time since Microsoft’s landmark antitrust case in 2001. The DOJ filed a case against Google over its search and search advertising business. The CEOs of Amazon, Apple, Facebook, Google and Twitter have also been called to testify before Congress, in some cases repeatedly.

Now, according to Politico, the five FTC commissioners have met to discuss an antitrust case against Facebook. The company has repeatedly been accused of stifling competition by purchasing smaller rivals it deems a potential or future threat. In addition, Facebook has faced ongoing criticism for its mishandling of user privacy.

Because of the confidential nature of the probe, Politico’s sources spoke anonymously. It’s unknown which way the FTC commissioners are leaning, and a decision is not expected for several weeks. Nonetheless, it’s the latest challenge facing Big Tech in general, and social media in particular.
