Comparing high school to a dictatorship is one way to confirm that you have very little experience with the latter. You do understand that if something is causing issues to the regime, then regime will simply make it illegal? Illegal to use, to posses, to buy, etc. — not like specifics matter here.
> Generally just don't come here anymore, but with the US fascists now checking phones at borders, the idea of having low detectability digital "smuggling compartments" (digitally speaking) in our devices is becoming all too real. Some loopback filesystem that your phone can mount that has the rest of the phone, various systemd-sysext layers for bitchat.
Even then, that's just wishful thinking. Only GrapheneOS has something similar right now, duress PIN/password (which isn't exactly designed for cases like this, but still) [0]. It won't help you much in a dictatorship, the police isn't that dumb — you'll be subjecting yourself to physical harm by using it. They know that your phone isn't empty, and they don't need anything to prove it. For them gut feeling is enough, laws and human rights are irrelevant.
Also, let's be realistic, Apple isn't going to have something like that on iOS.
