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.

What are you talking about? I mean trust in the sense of doing the right thing from a security aspect. Maybe whoever is setting up the server isn’t as adept with security and doesn’t do all that is required.

I suppose. You’re still putting trust into something. To make sure they’re doing the right thing and making the right decisions in regards to security and privacy, and that they wouldn’t be pressured by a government or third-party to violate that.

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.

Wouldn’t you have to trust that they’re not logging your IP and/or storing your messages?

Signal doesn’t store your contacts or messages; it’s end to end encryption. What are you suggesting they’ll “sell out” if offered enough money?
