Dark Patterns and the Law: What the FTC Has Actually Enforced

"Dark patterns" is the term researchers and regulators use for user-interface design choices deliberately built to manipulate users into decisions they wouldn't otherwise make — not ordinary persuasive design, but design specifically engineered to obscure, mislead, or create friction around the choice a company doesn't want the user to make. The FTC's 2023 lawsuit against Amazon, settled in 2025 for $2.5 billion, is the largest enforcement action built around this specific theory to date, and its details are genuinely useful for understanding exactly where regulators currently draw the line between aggressive marketing and illegal manipulation.

What the FTC Actually Alleged Amazon Did

The FTC's complaint, filed in June 2023, described a years-long pattern in how Amazon handled Prime subscription enrollment and cancellation. On the enrollment side, the complaint alleged Amazon used design techniques that made it unclear a user was agreeing to a paid, recurring Prime subscription at all — burying the relevant disclosure among unrelated purchase-flow steps, using visual emphasis to draw attention toward enrollment and away from the actual cost and recurring nature of the charge.

On the cancellation side — which became the more central element of the case — the FTC alleged Amazon built what internal company documents reportedly referred to, in a name that became widely reported once the litigation made it public, the "Iliad" cancellation flow: a deliberately long, multi-step, multi-page process a user had to navigate to actually cancel a Prime subscription, in contrast to how quickly and easily a user could enroll in the first place. The complaint specifically identified this contrast — near-instant enrollment paired with an unnecessarily long, winding cancellation path — as the core of the manipulative design being alleged.

The Settlement's Scale and Terms

Three days into the actual trial, Amazon agreed to settle rather than let the case continue to a verdict, for $2.5 billion — a figure the FTC described as one of the largest settlements in the agency's history. The settlement split into two components: $1 billion in civil penalties paid to the government, and $1.5 billion in direct restitution earmarked for the millions of consumers affected by the alleged practices. Beyond the financial terms, the settlement imposed forward-looking behavioral requirements as well, explicitly prohibiting Amazon from requiring customers to navigate confusing, lengthy, or unnecessarily difficult prompts specifically to cancel a subscription — a provision that functions, for Amazon specifically, much like a company-specific version of the broader click-to-cancel principle the FTC has separately tried to apply industry-wide through rulemaking.

Why This Case Matters Beyond Amazon Specifically

The Amazon settlement functions as a real, concrete demonstration of what the FTC considers actionable dark-pattern conduct under its existing "unfair or deceptive acts or practices" authority — authority that exists independently of any specific new rule and doesn't require a formal rulemaking process (unlike the click-to-cancel rule, which ran into exactly this kind of procedural requirement and got vacated on that basis). This distinction matters: even without a dedicated, formally promulgated dark-patterns rule in place, the FTC has demonstrated it's willing and able to bring — and win, or at least extract an enormous settlement from — a case built on this theory using its existing general enforcement authority.

The Specific Elements That Made This Case Actionable

Looking at what the FTC's complaint actually emphasized helps clarify which specific design elements cross from aggressive-but-legal into actionable-as-deceptive. The complaint's core theory rested on asymmetry and obscurity: making enrollment fast while making cancellation slow, and making the fact of enrollment in a recurring paid subscription unclear at the moment of sign-up rather than making the cost and recurring nature of the charge reasonably conspicuous. Design choices that merely encourage a preferred outcome — a highlighted "recommended" pricing tier, a prominently placed call-to-action button — sit in a different, generally uncontroversial category from design choices that actively obscure material terms or erect artificial friction specifically around the option a company doesn't want a customer to choose. The Amazon case is a useful marker precisely because its scale and its public trial record make clear which side of that line the FTC believed Amazon's specific cancellation flow fell on.

What This Means for Other Companies Going Forward

The size of the Amazon settlement, and the fact that it came from litigating rather than only from a general rule the agency wrote unilaterally, sends a clear enough signal that other companies with similarly asymmetric enrollment-versus-cancellation design have real, demonstrated legal exposure under existing law, independent of whatever eventually happens with the FTC's separately vacated click-to-cancel rule. A company relying on the argument "there's no specific rule against this" is on considerably shakier ground than that argument might suggest, given that the Amazon case shows the FTC's existing, longstanding unfair-practices authority was already sufficient to build a $2.5 billion case around exactly this pattern, without needing a dedicated dark-patterns statute to get there.
