Now wait a minute. Serveillance technology is definitely sold as more than just tools for building a house. They are tools of war and authoritarianism. Sure you have your run of the mill equipment for securing your building. But then you have massive networks of Spyware to catalog an entire nation's activity embedded without notice into the products you use without your consent. Your politician will sell you it for homeland security but the companies that sell the tech to the government sell in the same way arms dealers do. A Tomohawk missile is also a tool. And if home depot was selling that, especially if they were selling it under the pretence of a 'self defence tool' you but your shiny behind I'd have a problem with it. Wouldn't you?
Now consider home depot and Amazon are both warehouse businesses. Only one of them is helping the US government extend its digital spy network and increase its cyberwar capabilities.
