So you have nothing to hide, eh?
These tvs, like smartphones, track lots of stuff. And the databases they feed make all sorts of inferences.
They even scan what you’re watching from other sources and can determine what show it is, and report that info too.
They know when you’re home and leave, to some extent.
I’ve read of patents for wifi tech in tvs that will connect to other TVs of the same brand for a connection if you don’t set one up.
They definitely use their own DNS, and probably have some hard coded IPs so you can’t block them phoning home via DNS (I’ve tested this myself). I can see this traffic even when I setup DNS blocks - they still hit the vendor’s service IPs (looking at you, Samsung).
These companies are openly antagonistic and adversarial to us, and you “have nothing to hide”?
Right?
$450 and a toaster to use something like the external batteries I’ve used for a decade.
