That single point of failure is to facilitate ease of use, with minimal reduction in security.
The messages are e2e encrypted and the server is designed in such a way that attempting to listen in would bring it down.
The signal org doesn't even have your address book.
If your concern is "I don't like signal", you're not going to make much traction.
Briar is an app that is just as easy to use, plus you dont need a phone number, so it is easier. Yet it has no point of failure and it was simpler to write. It is P2P, uses tor, you dont get better privacy and security than that.
You dont know what their server is running, you cant prove that. They can release the code, but you have to trust them that they are running that exact code.
Ease of use is an excuse, they have a centralized model. That is a big flaw. There is more to security then E2E, xmpp clients have E2E as well, they use the same algorithm.
SimpleX also seems pretty promising and is more cross platform than briar. I'm self-hosting a server for my immediate family.
I think XMPP is more well-known than SimpleX, I simply mentioned Briar for the sake of possible ease of use argument over some XMPP clients.
I'm not goin to shit on Briar, I hope they build out their dream.
It's fundamentally not as easy to use.
My Grandma already has a phone with a full addressbook.
If she's told to install Signal, it'll just work as a drop in replacement for iMessage.
Briar meanwhile suggests sharing your contact info using another such as signal: https://briarproject.org/quick-start/#:~:text=When%20you%20choose%20%E2%80%9CAdd%20contact%20at%20a%20distance%E2%80%9D%2C%20Briar,choose%20a%20nickname%20for%20them.
Briar is chasing different goals.
The only part that is easier to use on Signal is also a serious privacy concern of sharing your phone number.
With decentralized apps you always have an option to add that feature, while with centralized apps like Signal you have to accept that your privacy is damaged.
In short, this argument for phone number is another argument why decentralized apps can be as user friendly as centralized, but not the other way around.
I see your point, but what threat and their level of sophistication are you trying to avoid? The number is used just for registration. You can get a burner phone if you're worried about sharing your number.
In less and less countries we are allowed to buy phones and sim cards without an ID. Phone network is a centralized system, controlled by governments, we can't depend on that for privacy. The main treat to privacy has always been the current ruling government, they fear privacy, because they fear people organizing against them.
I'll give you not being able to buy SIMs without an ID; I didn't know that. But the rest is not as accurate. You should probably just not use a computer or phone to ensure complete security.
I wouldn't if that was a viable option. Today it is not really possible to not use technology, even not using mainstream apps will make you socially isolated and unemployable (which due to lack of decent social services, is a death sentence)
I'm not OP, I'm just explaining.
