The investigation into Amazon’s Prime sign-up and cancellation systems began in March 2021, but gained momentum in 2022 when Insider obtained internal documents suggesting that Amazon was aware of customer complaints as early as 2017. The sign-up process encouraged customers to opt for a 30-day trial with a single click during checkout, but cancelling the service before the trial ended required navigating through multiple pages. Amazon even used the term “Iliad” to describe the lengthy cancellation process, drawing an analogy to the epic poem by Homer.
