Sen. Elizabeth Warren of Massachusetts on Friday called for the government to break up Facebook, Google and Amazon, offering a plan to re-categorize the companies and reverse some major tech acquisitions.
Warren, who is running for the Democratic presidential nomination in 2020, has been a part of a growing faction within the party that has called for greater regulation and antitrust enforcement of major tech companies.
"Twenty-five years ago, Facebook, Google, and Amazon didn’t exist. Now they are among the most valuable and well-known companies in the world," Warren wrote in a post on the blogging platform Medium. "It’s a great story — but also one that highlights why the government must break up monopolies and promote competitive markets."
Warren's call also comes as Democrats have begun to plan for increased oversight of tech companies after taking control of the House. On Wednesday, House and Senate Democrats introduced legislation to establish strong net neutrality protections that would look to prevent major service providers from using their power to manipulate how users experience the internet.
Few Democrats, however, have actively called to break up tech companies, as Warren did on Friday.
Warren said in her post that the consumer experience of most internet users is dominated by Facebook, Google and Amazon, which can then "use the Internet to squash small businesses and innovation, and substitute their own financial interests for the broader interests of the American people."
Warren's plan calls for legislation that would feature a new business category for companies with more than $25 billion of global revenue that also "offer to the public an online marketplace, an exchange, or a platform for connecting third parties." These companies would be called "platform utilities" and be prevented from owning the platform and any of its participants, as well as be required to "meet a standard of fair, reasonable, and nondiscriminatory dealing with users." They would also not be allowed to share data with other companies.
Warren pointed to Amazon's operation of its marketplace and its sale of Amazon "Basics" as an example of a violation of the proposed legislation. She also said that Google's various businesses would need to be separated, including its ad exchange and its search engine.
Warren also said that she would be looking to federal regulators to undo some recent mergers, including Amazon's ownership of the grocer Whole Foods and e-commerce website Zappos, Facebook's ownership of WhatsApp and Instagram, and Google's ownership of the navigation app Waze and home device company Nest.
"Unwinding these mergers will promote healthy competition in the market — which will put pressure on big tech companies to be more responsive to user concerns, including about privacy," she wrote.
Facebook and Amazon declined to comment on Warren's plan. Google did not immediately respond to requests for comment.
Luther Lowe, senior vice president of government relations at Yelp, which has repeatedly claimed that Google uses its search engine to scuttle competitors, said Warren's plan was "refreshing and ambitious."
"I think Senator Warren really understands how these markets work, and I think this type of proposal would inject some much needed oxygen into the consumer internet markets, which today are calcifying as a result of dominant firms like Google stifling innovation," Lowe said.
Warren is not entirely alone in proposing serious changes to how tech companies are regulated. Rep. David Cicilline, D-R.I., who heads the House antitrust subcommittee, recently suggested in an interview with the Financial Times a similar idea in which tech companies would be forced to split up their platform from their customer data business.
Dipayan Ghosh, a fellow at Harvard University's Shorenstein Center on Media, Politics and Public Policy, said that while Warren's proposal is in the "right direction," Cicilline's plan targets the heart of the power of big tech companies to use consumer data in conjunction with their platforms to control their markets.
"The reason I like Cicilline's argument is that one really does get to the meat of the way that these companies have been constructed," he said.
Ghosh, who previously worked at Facebook as a privacy and public policy adviser, said big tech companies have already been preparing for regulation efforts. He pointed to Facebook CEO Mark Zuckerberg's announcement on Wednesday that the company would be moving to make it so users can communicate across its various apps.
Ghosh said these kinds of efforts will make it hard to break up tech companies. He predicted that this is the start of a cat-and-mouse game between tech companies and regulators that will go on for years.
"I think what these companies are trying to do. especially Facebook, is figure out ways to really unsettle the competition policy arguments that are taking shape by doing strategic things with their companies," Ghosh said.
