How are state attorneys general leveraging consumer protection and antitrust laws to challenge Big Tech companies, and what are the key differences in their approaches?

State attorneys general have become the most active enforcers against Big Tech in the United States, often moving faster and with more coordination than federal regulators. Since 2020, dozens of states have filed or joined lawsuits against Google, Meta, and Amazon, pairing century-old antitrust statutes with consumer protection laws written for local retail fraud, not global ad exchanges. The Reuters coverage of this trend and Kelley Drye's ongoing tracking of state AG activity both point to the same structural fact: attorneys general answer to state legislatures and voters, not to a single national enforcement doctrine, so their theories, remedies, and coalitions vary. The Department of Justice's October 2020 case against Google, joined by a bloc of state AGs alleging exclusionary distribution deals, showed how state and federal enforcement can converge. But convergence is the exception. More often, states split into separate coalitions pursuing separate legal theories against the same companies, a pattern that reveals as much about American federalism as it does about platform power.

The core distinction is between two legal toolkits. Antitrust claims target market structure: monopolization, exclusive dealing, tying, and anticompetitive acquisitions. Consumer protection claims target conduct toward users: deceptive design, data misuse, and unfair practices that don't require proving market dominance at all. Ebsco's overview of the Google search case shows the antitrust route in its clearest form. The DOJ and a coalition of state AGs alleged that Google used exclusionary contracts with device makers and browser developers to lock in default search placement, a Section 2 monopolization theory borrowed straight from the Microsoft case two decades earlier. That suit required states to build economic evidence of foreclosure and harm to competitors, a slow and resource-intensive process.

Consumer protection statutes work differently. Nearly every state has an Unfair and Deceptive Acts and Practices (UDAP) law that lets an attorney general sue over misleading privacy disclosures, dark patterns, or harm to children without proving monopoly power. Kelley Drye's tracking of state AG activity through 2022 documents how attorneys general on both sides of the aisle have used these statutes against platforms over data collection practices, algorithmic amplification, and product design aimed at minors. This is where the sharpest partisan and regional differences show up. Democratic AGs in states like California, New York, and Massachusetts have tended to frame cases around privacy harms, data broker practices, and misinformation exposure. Republican AGs, led by Texas, have more often framed the same companies' conduct as viewpoint discrimination or censorship, sometimes filing suits or issuing civil investigative demands that read as much like political statements as legal complaints. Both camps use the same UDAP language, but the underlying grievance differs sharply.

Coalition structure adds a second axis of variation. Some multistate actions are broad and bipartisan, such as the Google search case, where dozens of states across the political spectrum joined a single DOJ-led complaint. Others split along partisan lines entirely, producing parallel or competing suits against the same defendant. Texas has led a separate multistate coalition against Google's advertising technology business, alleging a scheme to rig ad auctions, a case that proceeds independently of the DOJ's own adtech suit. Reuters' reporting on the broader enforcement trend notes that attorneys general have increasingly acted ahead of, rather than alongside, federal agencies, filing their own suits against Meta and Amazon rather than waiting for FTC action. That independence cuts both ways: it lets states move faster and tailor claims to local law, but it also fragments litigation, multiplies discovery costs for defendants, and raises the risk of inconsistent rulings across jurisdictions.

Remedies differ too. Antitrust suits tend to seek structural relief: divestiture of ad exchange businesses, unwinding of acquisitions, or injunctions against specific contractual practices. Consumer protection suits typically seek civil penalties, changes to disclosure practices, or restrictions on data use, remedies that are cheaper to obtain and easier to enforce but leave market structure untouched. A state AG weighing which statute to invoke is also weighing how much structural change it actually wants versus how quickly it wants a settlement check and a headline.

The result is an enforcement landscape that looks less like a coordinated campaign against Big Tech and more like fifty-odd legal laboratories running different experiments on the same defendants. Kelley Drye's update captures this directly: attorneys general continue filing new actions even as older ones remain in discovery, with no sign of the pace slowing regardless of which party controls a given state's AG office.
