>Signal works over the internet, and the internet requires IP (internet protocol) addresses in order to figure out where a message should go. But sending messages over the internet does not require phone numbers; that’s a requirement when using SMS or cellular calls or mobile data, but not for using the internet. And yet, the “privacy-protecting” Signal app requires you to use a phone number to send and receive messages…
>What that leaves us with is a single service that is still a work in progress: SimpleX. It asks for no global identifiers like phone numbers or email addresses. It at least tries, unlike Signal, to make sure that it doesn’t know who’s talking to who.
