The parent post is probably referring to Amazon Sidewalk, a mesh network formed from Echo devices and other Amazon smart ~~garbage~~ devices, launched in 2021: https://arstechnica.com/gadgets/2021/05/amazon-devices-will-...
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.
But I can't find anything now, so it might be best to consider it apocryphal.
