The Privacy Light That Learned to Tell Tales
The trick that made me sit up is this: Zoom can tell you are in a Google Meet without ever touching your microphone. No permission prompt, no audio capture, just a quiet check of what the operating system already wrote down. The finding is blunt: "Zoom uses macOS Control Center logs and Windows microphone privacy records to detect when other applications use the microphone." That is not a bug in Zoom. That is Zoom using your computer's privacy infrastructure as a radar.
