You forget that there's ethernet inside the HDMI (1.4 and up) cable, it's called HEC (HDMI Ethernet Channel)?

It can just take network from whatever is attached and connected.

While Ethernet over HDMI is certainly a thing, is there any chance of a TV actually doing that without a consumer jumping through several hoops? As someone who would actually like that as a feature, I am 100% sure my 4 month old TV isn't sneaking internet access through its HDMI connection.
