speaking as Matrix’s lead maintainer: we are focused on it powering decentralised and encrypted whatsapp (or teams) alternatives.

unsure what makes you think we want to build a next-gen tcp/ip, but can I have some?

building a more flexible solution for blocking content, rather than hardcoded rules like "no images": https://matrix.org/blog/2025/04/introducing-policy-servers/

No, it's just a warning that your client can't prove that the message was really sent by that sender. These will eventually go away once https://github.com/matrix-org/matrix-spec-proposals/pull/404... lands.

The main things are https://matrix.org/blog/2025/04/introducing-policy-servers/ (for flexible serverside moderation) and the rest of the stuff in https://matrix.org/blog/2025/02/building-a-safer-matrix/. Clientside filters already existed, but given they only apply per client and there are a lot of different clients, we focused on serverside filtering.
