In August, Meta settled with 47 American states for $17 billion, ending a trial over whether Instagram and Facebook were designed to addict children. The money made the headlines. The more interesting part is what else the states got, because every item on the list is a design decision.
Under-18s now get a default daily limit of two hours, and only a parent can lift it. Like counts are hidden for young users. And there's an optional non-personalised feed, which is a polite way of saying the algorithm built to keep you scrolling comes with an off switch.
Nobody was ordered to write a policy or hire an ethicist. The court's remedy is a settings screen.
Design was the charge. Now it's the sentence.
California's filing in the Meta case openly borrowed the tobacco playbook. But look at what tobacco actually got: warnings, taxes, advertising bans. The cigarette itself never changed. Here, the product is the thing that changes. "Addictive design" was the accusation, and the punishment is a redesign.
That's new, and the design industry did some of the groundwork itself, mostly without noticing.
In 2010 a designer named Harry Brignull started cataloguing the tricks interfaces use to make people do things they didn't mean to do. He called them dark patterns, gave them names, and built a public hall of shame. Confirmshaming, where the decline button reads "No thanks, I like paying full price". Sneaking items into baskets. The roach motel, where getting in takes one click and getting out takes an expedition.
At the time it looked a little like industry self-criticism, a designer keeping a list of his profession's sins. It turned out to be something more useful: a vocabulary. Courts can't order remedies for vibes. They can order remedies for named, documented, repeatable patterns, and by the time the Federal Trade Commission published its own report on the subject in 2022, it was using Harry's taxonomy more or less wholesale.
The roach motel is the classic of the genre, and it has already had its day in court. The best-known case involved cancelling an Amazon Prime subscription, a process the Federal Trade Commission says was codenamed Iliad internally, after the ten-year war. It settled last year for $2.5 billion, with an obligation that cancelling be as easy as joining. A design pattern with a name and a paper trail is no longer a growth tactic. It's evidence.
The regulators learned to use design
Two earlier cases show how deliberate this has become.
The United Kingdom didn't ban online slot machines. It began deconstructing them, feature by feature. From October 2021 the Gambling Commission banned autoplay, banned spins faster than 2.5 seconds, banned the turbo and slam-stop features that compress time, and banned the celebration sounds that play when your "win" is smaller than your stake. Your losses and session time now sit on screen while you play. And a withdrawal can't be cancelled once requested, which killed the pattern where your own money sits there for days, asking to be re-gambled.
None of that is a warning label. It's a slower, quieter, more honest machine, specified by a regulator paying attention to the behavioural tweaks that lead us towards gambling addiction.
The other case changed an industry without a single trial. The United Kingdom's Age Appropriate Design Code, in force from 2020, produced, by one count, close to a hundred design changes across the platforms. YouTube switched autoplay off by default for under-18s and turned bedtime reminders on. Instagram made teenage accounts private by default. TikTok stopped sending children push notifications at night. On paper it's a privacy code. In practice the regulator forced the reversal of those insidious designed elements that game our attention so that we lose ourselves in the moment.
Put the remedies side by side with Harry's list and you notice the symmetry. The catalogue of dark patterns reads like a charge sheet, and regulators are now working through it in reverse. Autoplay, banned twice over. The roach motel, dismantled by court order. Fake urgency, under investigation at the Competition and Markets Authority, whose drip-pricing cases against Trainline and Virgin Atlantic set a design standard in one plain sentence: the first price customers see should be the price they pay.
Where the flip is overdue
Which raises the question the settlement doesn't answer. If courts now treat interface design as the site of harm and the instrument of remedy, where else should they be looking?
Money apps, for a start. Buy-now-pay-later checkouts routinely make the instalment plan the default and the full price the effort. Every principle in the drip-pricing cases applies to that screen, and none of it has reached it yet.
Debt collection, where Australia's consumer regulator recently fined a collector for the shape of its process, demanding payment while leaving disputes unanswered, separately from any false claim it made. Regulating the choreography of a process rather than the truth of its statements is design regulation in everything but name, and it's just getting started.
And gig work apps, which borrowed streaks, quests and surge pings directly from the slot machine and applied them to people driving cars through traffic. There's a 2.5-second rule for a spin of the reels. There's nothing for the ping that sends a tired courier back out.
The toolkit was never the problem
A default, a time limit, an autoplay setting: each one is a lever, and it works in whichever direction you pull it. For twenty years the money pulled the engagement lever, and the results were profitable enough that the tricks got names, then case names, then codenames.
What the Meta settlement, the slots rules and the Children's Code have in common is that someone with power pulled the same levers the other way, and they worked just as well. A default can hold you in or let you out, and either way somebody chose.
The list of what's been fixed is short. The list of what hasn't is everyone's lived experience: the subscription you gave up trying to cancel, the countdown timer that reset when you refreshed the page, the app that buried the one setting you actually wanted.
So that's my question. What have you used, or been made to use, that you'd hand to a regulator first?
