Try WireMin, I’ve been using it for a month, E2EE for dms, voice call, chat rooms, feed, pic or file transfers, P2P network. Its different with Signal/Telegram, which are run by a single company and could exit the UK if they have to. It is decentralized, it can’t be controlled or banned by anyone.

True, and Anonymity is important as well, I am suppose to recommend Mastodon, etc. But they do require Email address as an identity verification.

Nostr https://www.nostrapps.com/ or WireMin http://wiremin.org/

Both of them are decentralized social media, and does not require personal info to register.
