> some devices expose ethernet over HDMI

wait, is this really a thing? I've heard about hdmi over ethernet, but ethernet over hdmi? also it seems it would be a lot trouble to bridge the wifi connection and dhcp to this ethernet over hdmi interface, why should they do it?

Yes.

Using Ethernet to communicate between the connected devices doesn't mean that either device is acting as a router to send packets beyond that direct link.

TIL! doesn't seem it really gained any popularity though to be really a security concern
