Quick Take: Beyond the Lock Icon
When you open these three messaging apps, you'll see the exact same reassuring lock icon. But those identical locks are guarding vastly different data ecosystems. People often assume that if an app says encrypted, their conversations are automatically immune to leaks or surveillance. That is a dangerous misconception.
