You just made me wonder if those smart TVs have the ability to packet sniff what’s going on on the Wi-Fi networks in the homes in which they’re installed.

Some IOT devices definitely do scan your network automatically to look for other compatible members of the ecosystem.

from wikipedia "HDMI Ethernet and Audio Return Channel Introduced in HDMI 1.4, HDMI Ethernet and Audio Return Channel (HEAC) adds a high-speed bidirectional data communication link (HEC) and the ability to send audio data upstream to the source device (ARC). HEAC utilizes two lines from the connector: the previously unused Reserved pin (called HEAC+) and the Hot Plug Detect pin (called HEAC−).[51]: §HEAC-2.1 If only ARC transmission is required, a single mode signal using the HEAC+ line can be used, otherwise, HEC is transmitted as a differential signal over the pair of lines, and ARC as a common mode component of the pair." HDMI Ethernet Channel (HEC) HDMI Ethernet Channel technology consolidates video, audio, and data streams into a single HDMI cable, and the HEC feature enables IP-based applications over HDMI and provides a bidirectional Ethernet communication at 100 Mbit/s.[43] The physical layer of the Ethernet implementation uses a hybrid to simultaneously send and receive attenuated 100BASE-TX-type signals through a single twisted pair." https://en.wikipedia.org/wiki/HDMI https://en.wikipedia.org/wiki/HDMI -------------------------------------------------- This gives me the impression that packet sniffs, and many other operations have been in play since HDMI 1.4, possibly a subscription based desktop as a service, or game console as a service, could distribute this way, and leech off local LAN gateway, for heavy loads.
