I have moved my communications to SimpleX for very similar reasons.

I always found Matrix to be extremely clunky because of key management for rooms and stuff like that.

I'm used to using cryptocurrencies. I know how to manage keys, and yet I was constantly getting hit with the same issues with decryption of old messages, even when I properly saved my keys and imported them.

I figure if I'm not even able to use this thing properly, knowing and understanding technology, how do I expect people I talk to to understand how to do it properly?

Then, on top of that, I found out about all the metadata leaking to your home server. Sure, your communications might be encrypted, but if the sender, receiver, reactions, timestamp, etc. is not encrypted, that's not good.

I still have it on my device, but it very rarely gets opened anymore.

Edit: I use a combination of signal for those I know, IRL, and simplex for groups of FOSS enthusiasts, etc.

How are you using Simplex as a replacement for Matrix? That's not a leading question - I'm curious about the use case.

I stopped using Matrix for 1:1 and family chat years ago because of how broken encryption has always been, but I've kept using it for public chats since

  • privacy isn't solvable in public chats, so the fact Matrix's encryption is terminally screwed up isn't relevant
  • there are many public rooms; not IRC-level, but it's still a large domain with large numbers of users
  • Matrix is a better public chat than IRC (fight me!) with replies, comment editing, reactions, emojis (that's mostly a client thing, but it's first-class and not a sporadically supported feature), and offline history syncing (as in, see what happened while you were offline).
  • I haven't yet found anything that's as good at public rooms as Matrix, that's still federated and OSS. Discord is very good, but it's SPA crap and centralized to boot.

SimpleX seems to be focused primarily on messaging, not public, large group chat... but am I missing something?

Yes you're missing a lot. SimpleX even has a directory bot to find public group chats.

Is ðis right? In a group wiþ 6k members, each message posted to ðe group is 20MB of traffic? I suppose ðis is a consequence of ðe E2E design - a message posted sends a message to 6,000 people, individually encrypted and delivered?

Screen shot of a group wiþ 6k+ members, warning ðat each message causes a 20MB payload

Do you happen to know ðe plan for addressing ðat? It seems like a fairly large impediment, and I can't imagine what a solution would look like ðat preserves E2E.
