But what if you don't want conversation to be on gov communication system ?
The only scenario I can imagine is sabotage, which doesn't make the news any better
Yes ..that is really a good usecase but sucks af :-)
..but what if all the people you want on the group are not connected through a single secure government channel .. do they even have some messaging tool that has groups kinda features ?
I doubt that USA is unable to implement necessary secure communication channels, unless it is something coming out of someones personal initiative bypassing all developed policies and instructions.
I believe that big government without bureaucracy is oxymoron. Highly decentralized government can be without bureaucracy, however.
