I’ve always wondered if the world’s major governments all have their own secret, bespoke operating systems for highly sensitive situations. Like, not Windows, Linux, macOS, BSD, or anything even remotely known to the public. But then you see high-ranking admin officials using bootleg Signal on an off-the-shelf phone or whatever.

I’d assume the actual intelligence agencies are more sophisticated. I doubt they’re running some “hardened” version of Windows or Android or whatever. But maybe I’m being naive and they all are just working with vendors.
