Again Back to this statement: > What I'm not fine with is being forced to use Slack for work-related material. You don't want such sensitive data centralized. You want to host such yourself The moment you use IRCCloud all that sensitive data is on IRCCloud’s servers. How does “building a protocol in top of that (on top if what?)” help?
The point is that those who own the channel and/or server can enforce E2EE. They own the data. Its also possible someone on an IRC client is running a compromised server. Then you're also back to square one. Given we're talking in circles I'll withdraw from this discussion.
How can they enforce E2EE if very few if any IRC clients support it?
What good does “owning the data” do if the data ends up on IRCCloud’s servers anyway (companies who use Slack also own their data).
It’s quite telling that people have such a strong belief in the magic of protocols.
