Telecoms shut down 3G once 4G had rolled out. TV networks killed DVB-T after DVB-T2 went live. Banks have abandoned FinTS for app-based 2FA.
Your comment compares a paper-based, non-digital process with a digital one. My criticism, however, is about abandoning an old digital (but vendor-neutral and inclusionary) process in favor of a new (and discriminatory) one.
