governments can't keep up with encryption so expect them to counter via hostile tactics to compensate. it's all they've left.
corrupt french politicians have just legalized spying on protestors - very common anti-protest tactic now - compromise phones: track location, activate mics and cameras, read messages
if you are protesting - anywhere in the world - leave your phone at home - if you need comms consider radios or buy a burner with cash
for secure messaging I recommend signal or simplex - disappearing messages enabled just in case someone gets arrested

Violence and coercion are the primary tools of the State. Everything else (secret police, euphimism, bribery of the people, etc)is an attempt to hide that.
