Source? This sort of conspiracy started with "smart tvs will connect to open wifi networks", then evolved to "it uses amazon sidewalk", and apparently now morphed into "tvs have 5g modems". Given how poorly supported the prior claims were, that does not bode well for the 5G claim.
Sounds obvious for TV manufacturers to do this if they plan to spy on you and sell ads you can't hide. Same with locking down firmware.
Every time the topic is TV on HN someone repeats this conspiracy or that "it'll happen soon!"...
This place like a flat-earther gathering sometimes.
Isn't that one of the marketed advantages of 5G. Lot of smart IoT devices including TVs being able to connect independently.
What we are lacking is implementation but the tech and probably the intent was always there. If HDMI ethernet connectivity(HEC) had gained traction, we would have seen a fire stick, apple tv or roku providing internet to your tv without asking for explicit consent.
