Here's Warren's actual proposal:

https://elizabethwarren.com/plans/break-up-big-tech

First, by passing legislation that requires large tech platforms to be designated as “Platform Utilities” and broken apart from any participant on that platform.

Companies with an annual global revenue of $25 billion or more and that offer to the public an online marketplace, an exchange, or a platform for connecting third parties would be designated as “platform utilities.”

These companies would be prohibited from owning both the platform utility and any participants on that platform. Platform utilities would be required to meet a standard of fair, reasonable, and nondiscriminatory dealing with users. Platform utilities would not be allowed to transfer or share data with third parties.

For smaller companies (those with annual global revenue of between $90 million and $25 billion), their platform utilities would be required to meet the same standard of fair, reasonable, and nondiscriminatory dealing with users, but would not be required to structurally separate from any participant on the platform.

To enforce these new requirements, federal regulators, State Attorneys General, or injured private parties would have the right to sue a platform utility to enjoin any conduct that violates these requirements, to disgorge any ill-gotten gains, and to be paid for losses and damages. A company found to violate these requirements would also have to pay a fine of 5 percent of annual revenue.

Amazon Marketplace, Google’s ad exchange, and Google Search would be platform utilities under this law. Therefore, Amazon Marketplace and Basics, and Google’s ad exchange and businesses on the exchange would be split apart. Google Search would have to be spun off as well.

Second, my administration would appoint regulators committed to reversing illegal and anti-competitive tech mergers.

Current antitrust laws empower federal regulators to break up mergers that reduce competition. I will appoint regulators who are committed to using existing tools to unwind anti-competitive mergers, including:

Amazon: Whole Foods; Zappos

Facebook: WhatsApp; Instagram

Google: Waze; Nest; DoubleClick

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 also isn't just going after large tech companies. She's also going after large banks and ISPs. It's laughable to claim that she isn't on the side of the American consumer after she almost single handily spearheaded the CFPB.

I'm sure big pharma is covered too. Aside: I have no idea what a President Warren would realistically be able to enact, but her goal is not to destroy the free market. Recall that she was a Republican for a long time. She wants to use government as a referee to ensure fair competition in the market, and to fill in the gaps the market doesn't provide. That's my take on her anyway.
