> When you say "Each group of users can have their own servers" you aren't enhancing privacy you are standing out.
You're also hedging against mandated government backdoors.
A single organisation like signal can easily compelled to add a backdoor (or leave the territory) like the EU is trying to do. Going after thousands of servers individually is a whole different problem.

Let's see the law that allows compelling backdoor into Signal then. AFAIK https://en.wikipedia.org/wiki/Bernstein_v._United_States established code as speech, meaning compelling backdoor is compelled speech, which goes against the first.
https://en.wikipedia.org/wiki/Code_as_speech goes into this in more detail and mentions https://en.wikipedia.org/wiki/Apple%E2%80%93FBI_encryption_d... where the defense was used.
GP already mentioned the EU as an example.
Yes or Canada
And also, do we really trust the US government on this after Snowden?
The rule of law is over.
