Unless I'm misreading it, the title of the HN link and the article's meaning don't match. "Mastercard will stop free trials from automatically billing once they're over" is not the same as "merchants will be required to send the cardholder [a message] with explicit instructions on how to cancel a trial." The former implies you can't do recurring payments where the initial payment was a non-capturing authorization. The latter implies, well, mastercard expects you to get an email from your vendor (e.g. your newspaper or whatever). I suppose said email could be as obtuse as "See website for subscription information".
