Quack is a tool to fight the echo chambers we all find ourselves in. Next time you're searching support for your arguments, whether on Google or YouTube or Bing (or even Yahoo), click the little blue duck icon in your browser. It will automatically open a new tab with opposing content for you. If we're going to find out what's really true, we're going to have to take it upon ourselves to practice better information hygiene. Stay safe, and expose yourself to strong arguments from all sides, always! * FYI, duck's quacks echo just like any other noise. The idea that they don't is fake news.
