Ah thanks for the answer. What's the PKI story on bluesky, doesn't every identity have a corresponding public key? So if I had a list of people I wanted to a post to be visible to, couldn't I "just" encrypt it with a key that is decryptable by each of those individuals via their pubkey?
I'm not really familiar with that layer of things, but I think it's possible, though that "just" is doing a lot of work here of course, and I think it might not necessarily be a good idea to have encrypted messages available publicly for everyone all the time, so they can collect them and wait until someone slips up / a vulnerability is found / they have enough hardware to crunch it...
PKI distribution for encrypted data is an unsolved problem at the scale of many millions or billions of people. Signal caps at 10k iirc
It's also generally not advisable to make your cypher text publicly visible
That being said, I'm working with others in the ecosystem on "permissioned space", which are much closer to how people think about Google Docs and similar systems working.
There is also another effort around E2EE content (MLS) for messaging. They are also thinking beyond just messages too
