The authoritarians control the streets. Where exactly are you going to go in an authoritarian system where you won't have to rely on something under authoritarian control? The authoritarians control you, that's why you're in the streets.

Yes, of course.

One should assume nothing. However, an even dumber idea is to advocate for a system to have more control, actively or by remaining silent, and then later stew in fatalism to the point of thinking that using a smartphone in a revolution is "dumb."
