This is basically admitting that consumers don't actually value their subscription service for the cost. If users were buying used bikes and signing up for subscriptions Peloton would be thrilled, they would do everything that they could to encourage that like free trials. But it must be that most people who buy used bikes don't find the subscription worth it and cancel within a few months. Adding this fee both extracts more money and creates a sunk cost fallacy that will cause them to go longer before cancelling.

If the product sold itself they would just let people pay them subscriptions, its basically free money.
