This comes just a few weeks after fb were shown not to be able to implement door access badges to their own buildings in a safe and secure way. Why would I ever trust a company like fb with hardware in my home/interacting with devices?
Downvoted but if it was a smaller startup trying to do something related to hardware they would be shorted to hell & back + would be the running joke of the year. "X is trying to sell secure VR headsets but they can't even work a security pass on their own building" and so on. See thread:
