Literally every single time government create a communication system the first thing they do is to make sure they can read it completely breaking the overall security. Look at all the state version of 'email' non of them used end-to-end encryption. Germany had a nice example but of course the project crashed and burned.

Also, its simply false that the market has not produced good solutions and if there was a 'unified message solution' then people would cry 'monopoly' and demand government regulation as well.

The fact is that the standard tool for most people use for messaging in Europe is an incredibly secure protocol.
