This feels a lot like saying that the reason why I can't put things up on the internet for a couple dozen close friends to read is because it'd be hard to implement the same thing for a news syndicate. Surely there's a middle ground somewhere.
@dynamic @koteisaev Each of us has several hundred followers, which is not infeasible but already an order of magnitude more than a couple dozen.
I'm not clear on whether ActivityPub supports the idea of posting to subgroups of followers, but Mastodon certainly doesn't, so this would be another feature entirely. I suppose if that were in place, you could say "E2EE only works with small groups" but it's not very satisfying.
@varx @dynamic @koteisaev Isn't E2EE just dependent upon the receiver having a key, so there is practically no server involvement? Maybe receiver identification or message acceptance is the issue? Maybe I should go RTFM.
I guess what I'm saying is a message could show up that looks like garbage to those without a key.

In fact there was a brief interval when Facebook was still using XMPP/Jabber and I was able to use Facebook messenger to send e2ee messages using Pidgin's "OTR" encryption. You can also still use Pidgin do that on Discord, I confirmed. But it relies on having someone on the other end who's set up with the right kind of client, which is nearly impossible to scale up, for social reasons.
