If there’s a way to filter out the analytics traffic and connections routed through the Echo after the router but before the connection to the modem/ont, this would be a good opportunity to build a simple device which blackholes this traffic. I’m thinking of a device that you simply connect between your home router and the connection to the isp. We all here can probably figure out a technical solution that works for us, but is not easy for the average person. I’m imagining a turn key device for the average person who is concerned with their privacy and doesn’t want the whole world using their internet connection.
