I share most of your sentiments, I really do. In a perfect universe, we'd all be using fully e2e-encrypted messaging systems. But:

> The only decision people need to make is centralized or decentralized system.

They already have this choice; Matrix and others exist for quite some time already. Yet it is evidently clear that your average citizen will flock to whatever messenger is the easiest to use and is already used by their friends/family. Security/privacy are second thoughts at best, if at all; and even if it were important, grasping the different implications of all the available options isn't exactly easy either.

And since we can probably agree that the vast majority of folks already "fail" to make the right choice in this regard, I'd much rather have a regulated, government-controlled messenger than some company like Facebook. The former is accountable to its citizens, the latter to its shareholders - if I have to pick my poison, the choice is clear.

> Are you seriously comparing letters and private IM conversations? I don't know about you, but I received/sent maybe 5 letters in last 10 years, none of which were from/to another private entity.

...because email and IM exist. they used to not exist and people sent paper letters to each other all. the. time.

now there are places and people I need a particular digital post office company to communicate with - and the worst part is, it's because they don't really care and thus force me to risk giving up my data if i want or need (read - am forced to due to life circumstances) to talk with them.

I think this trust difference is a general division between Europe and US. Europeans generally trust their governments more than private companies, and vice versa in the US. I would assume both have valid reasons for this on their own side of the pond.

For what it's worth, I too would trust the government a whole lot more than Facebook.

It seems most people have chosen the centralized system, whether we like it or not. So then, the next choice would indeed be „public or private“?
