Fediverse

I really want a Facebook (the old Facebook timeline) replacement, but end-to-end encrypted, and decentralised so there's longevity.

Edit for clarity: I'm looking for a way to share things online, end-to-end encrypted to a wide-audience that knows you but doesn't necessarily know each other.

This is why messaging apps don't fulfil this requirement, and chat rooms (like Matrix) also don't fit.

I love Lemmy, I like the idea of Mastodon (twitter-like sites just aren't my thing. ActivityPub rocks. However, none of them are encrypted.

PixelFed is neato, but I don't plan sharing my personal photos with the whole of the internet, which seems to be the only choice with ActivityPub.

Signal and other encrypted messaging apps are great, but are for direct messaging. Where are the encrypted social media apps?

Matrix is cool and all, but it's aimed at groups. Like discord / MS teams replacement.

Someone told me about Futo Circles, which seems to tick all the boxes and built on top of Matrix, but it's currently abandoned.

Are there any other alternatives? My wallet is open, I would very much like to use such an app. I am no programmer, so sadly cannot take on the mantle of continuing the Futo Circles project.
