What's the worst dark pattern you have seen in consumer apps?

I will go first- sneaking in membership fees while making a purchase; urban company recently got some flak for it.

Uber designers (or PMs) why are you trying to get rid of the ride search cancel button? Found a ride faster and cheaper ride on Namma Yatri but can't cancel until Uber decides it's ok to do so! Won't be surprised if this leads to accidental bookings and shifting the onus on the rider to pay a "cancellation" fee. Why chase vanity metrics at the expense of the user experience? Switchers gonna switch.

I think DrinkPrime is the worst designed app that also does not work when I am trying to recharge it...

- The FTC, along with international consumer protection networks, released a study on manipulative design techniques in subscription services. - Analyzing 642 websites and apps, the study found nearly 76% used at least one dark pattern, with 67% using more than one. - Common dark patterns include sneaking, obstruction, nagging, forced action, and social proof, often making it hard to cancel subscriptions. - The report suggests the FTC may increase focus on consumer fraud related to dark patterns. - The study involved 27 authorities from 26 countries and was part of the International Consumer Protection and Enforcement Network’s annual review.
