Use Signal, Use Tor
.... some caveats
At times when people are likely to be out protesting or performing acts of civil disobedience all the advice comes out about how to conduct good OPSEC. Some advice is good, some is bad, some is well intentioned, and some it just dangerous.
We often hear "Use signal, use tor" mentioned. It has become a mantra uttered both ironically and unironically as the goto advice from a number of people. But this lacks context, nuance, and a key bit of information.
