Senator Elizabeth Warren (D-Massachusetts) is proposing “a regulatory plan aimed at breaking up some of America’s largest tech companies, including Amazon, Google and Facebook,” according to The New York Times. “The proposal … calls for the appointment of regulators who would ‘unwind tech mergers that illegally undermine competition,’ as well as legislation that would prohibit platforms from both offering a marketplace for commerce and participating in that marketplace.” The plan would also call for the rollback of tech acquisitions, “including Facebook’s deals for WhatsApp and Instagram, Amazon’s addition of Whole Foods, and Google’s purchase of Waze.”

In addition, companies would no longer be permitted to share user data with any third parties.

“I want a government that makes sure everybody — even the biggest and most powerful companies in America — plays by the rules,” said Warren. “To do that, we need to stop this generation of big tech companies from throwing around their political power to shape the rules in their favor and throwing around their economic power to snuff out or buy up every potential competitor.”
