Fear mongering of MS watching everything and listening to everything you do killed the kinect. That's really it, the xbox 1 lit a fire under up the and coming social media boomer kids with there is a console for you and that narrative ain't left yet. It's a permanent black eye. In 2023 though we have our phones listening to us 24/47, they track as we actually agree to TOS that state they can take control of the camera and that they own all items that are run through said app. App's tracking your girls period, that take your health and Vitals and apps that store all your passwords and private info...
But hey, at the time, "Kinect might be on and listening to me in my living room or bedroom" meanwhile we asking "Hey Alexa/Siri/Bixby/google what is my bank account balance"
Man! The kinect had so much potential, I have some of my best memories on the xb1 playing some silly connect games as well as dance central with friends.
