>The rule change will require merchants to gain cardholder approval at the conclusion of the trial before they start billing. To help cardholders with that decision, merchants will be required to send the cardholder – either by email or text – the transaction amount, payment date, merchant name along with explicit instructions on how to cancel a trial.

Note the "... instructions on how to cancel a trial". I read this as signifying auto-charging commences at end of the trial. And merchants can continue forcing customers to jump through whatever hoops they had set up already. The only new requirement from MasterCard is sending of an email shortly before the auto-charge.
Am I wrong?
