I don't think that's the same. Amz Sidewalk is very slow, low bandwidth over sub-GHz. What GP is thinking about is probably along the lines of, if not getting Internet access by the owner, willy-nilly connecting to any open wifi network it finds, and uses that.

But "meshing" with other apparatus from the same manufacturers is a clever and evil idea - perhaps another TV from the same brand is in range and has Internet, then they can proxy that way.

All these probably break some regulations or laws.
