I trust governments less than companies because governments have thousands of years of history attesting to their ability to commit genocide based on ideology. Governments have killed millions because of ideas! Companies don’t have an incentive to kill their customers. And, a free market leads to people being able to choose to buy things from companies they like or refusing to buy dangerous products. People rarely have a choice in their government. Governments are inflicted upon people without a lot of power to stop them; companies can die relatively easily if they aren’t serving their customers.
