Use Tor Browser. Don’t waste your life on micro-optimisation. You will get a lot more privacy with stuff like getting all your friends on Signal/SimpleX, etc.
Do they really think we believe any of their lies? We don’t control macOS, iOS, anti-libre software (it fails to include a libre software license text file, like AGPL). Dangerous! 🚩
My friends knew I was using it. I said why with very simple words, focused on freedom and abuse over side effects, privacy and security, and they joined. I guess having friends who actually respect you helps a lot.
SimpleX is libre software and the most decentralised voice chat here.
Briar is libre and the most decentralised but is missing voice chat.
XMPP and Matrix are libre software and federated/decentralised. XMPP servers use far less resources, so creates more decentralisation than Matrix in practice.
Signal is libre and more popular but centralised, acceptable.
Avoid Threema’s app which requires a service as a software substitute.
