“Ironically, Moxie Marlinspike worked at Twitter and actually wanted to do encrypted DMs several years ago, [but] was denied that and then went and created Signal,” Musk said.
Musk went on to say that “we also want to have the ability to do voice and video chat via DMs.” He admitted that starting a thread on Signal needs the exchange of a phone number and that, owing to its account structure, Twitter can support encrypted calling “so that you don’t have to give someone your phone number.” Signal has said since 2020 that it is trying to transition away from reliance on phone numbers, yet this capability has yet to be implemented.
