Tinfoil OS
censiCLICK discusses two computer operating systems favoured by Edward Snowden, bête noir of the US National Security Agency. I had heard of neither Tails—which doesn't even need to be installed on a computer—nor Qubes OS before, so at least I can consider myself to be more knowledgeable.
I'm also somewhat relieved that, even wearing my tinfoil hat, I can make do with macOS. It certainly makes life easier. Clearly, Snowden's using military-grade tinfoil, rather than my more pedestrian supermarket-grade turkey wrapping.
