I think the text is somewhat dubious in its arguments, but this (and the arguments built on this assertion) is just plain wrong:
[Signals servers have] a few important pieces of data;
Message dates and times Message senders and recipients (via phone number identifiers)
Signal clients implement the Pond protocol. As a result, Signals servers know who a message is for (obviously, how else do you get the message) but cannot know who it is FROM.
I’ve been playing around with implementing a secure/private messenger demo for myself, and have been consistently impressed with how privacy preserving Signal is when reading their papers and code. I wish it was selfhostable, but apart from that, it’s great.
The server would be NICE to be OSS, but ultimately, privacy breaches are prevented client/protocol side.








Neovim, configured entirely through nixvim. I always liked neovim, but it’s never been as incredibly stable as now with nixvim.
Main/only IDE both in private and at work. Can’t ever go back, muscle memory has ensured that.
