The problem here is even the device owner is not the "administrator" of the device as we have lost ownership rights, locked behind EULA's, Patents and copyright The point of the original story is "your" meaning a device you own, is ignoring your network controls it is highly unlikely that the TV manufacturer is going to allow me to install my own custom root certs to inspect their traffic to HTTPS, so yes DoH and other things are a threat to network security, because if the TV become compromised I have limited administrative controls to prevent it other the blocking it completely which is a poor response to the problem DoH is a solution in search of a problem that can be solves in better more user friendly ways
