Privacy is one of the most basic human rights. When we talk to our loved ones at home, usually no one will hear us. But when we cross geographical barriers and chat through chat software, there may be someone who has been listening. When things go from offline to online, this kind of change that makes everyone uncomfortable should not happen. We should be thankful that many people are fighting for this right for themselves, and that Signal can be an important tool to maintain our privacy online.
