The full picture is that Signal has the most important piece of information you can give anyone online: your phone number (which means your real name and current address). Also that they’re hosted in the US and have close links to the US defense industry.













This is incorrect. They also have your full name and address by extension, as well as those of everyone you communicate with.
They’re also subject to national security letters, meaning the US state can get that info without a warrant.
Just read the first article I posted, it gets into all this.
The 2nd article is the signal CEO Meredith Whitaker interviewing with lawfare, which is a US defense industry think-tank.
