I have a VR headset from Facebook that is on its own VLAN because it defaults to randomizing its MAC address by default and this allowed it to bypass the firewall, phone home, and nonconsensually install new anti-features after being blocked because the setting got reset back to random when changing something.

That is infuriating and I’d do the same.

Plenty of reports of devices like LG TVs acting as gateways to external devices and LG in particular seems to be a privacy nightmare. I bought a couple of appliances that advertised their smart features only to find LG’s app was required, so LG actually required both Internet access AND my exact location at all times for the app to work at all.

You may be right to be concerned even about printers though. At some point we’re going to be reading about some built-in AI hacking other network devices for Internet access and transmitting our private information to the world.
