Hidden Subscription

No operable specimen exists yet; the illustration is editorial. Before applying this to a product, verify whether cadence and first-charge date actually appear near the commitment control, whether trial-to-paid reminders are actually delivered, the real visibility and step count of the cancellation entry point, and the specific negative-option and auto-renewal disclosure requirements of the relevant jurisdiction.

  "repair": "Disclose price, cadence, first-charge date, and cancellation method next to the commitment control, remind people before a trial converts to paid, and make cancelling as easy as signing up."

Different from obstruction: obstruction concerns an artificially hard exit path, while this entry concerns whether informed consent was obtained when entering the commitment; the two often co-occur but should be logged separately, and recurring billing should not be folded into either the hard-to-cancel entry or the one-time-fee entry.",
