Thats why the Linux kernel has a massive amount of CVEs, its extensively audited and researched.

Im not a security researcher tbh and I havent extensively studied the security model of Signal (I use Matrix)

Heres a list of all current CVEs

Fundamentally the biggest security vulnerability in every peice of software is the end user. It does not matter how intelligently the software is designed, no amount of preparation can handle the users. That is not to say Signal has no security vulnerabilities but almost nothing can stop someone from inviting a random reporter (if they explicitly invited them). Furthermore I have a conspiracy theory of sorts, I dont think it was a mistake. I think Trumps own administration is trying to backstab him. Maybe they had ideas of becoming more powerful, maybe they thought Trump would reduce their power, but I feel that the amount of government leaks and just how complicated they are would suggest infighting.

Blahaj and estrogen is also required along with a spiny skirt :3

I refuse to support them after they kicked Second Thought off the platform for supporting Palestinians over the GDF

I use GraphineOS on my Pixel 7 and even I feel penalized for caring about my privacy. Its absolutely nonsense, not everything needs an app.
