@Gargron @Sir_Osis_of_Liver mail servers must comply with ISO/IETF open standards to make SMTP protocol symmetrical, interoperable and independent from the service provider. In a similar way, phone networks must follow ISO/ITU open standards. International no-profit standardisation entities prevent bigger companies to take advantage of a technology against public interest, and I hope that an international standardisation entity for social media platforms will rise asap.
