Once the manufacturer sells the TV, they don't give a fuck about you anymore, they're already paid! Though they would like to push updates to send you more ads and track you.
I've never attached my 2020 LG 4k 65" to any network and it works great. I did pay $50 to add a GoggleTV CrapCast thing, it works fine for watching movies.
As luck would have it, https://rootmy.tv came out for Web OS. It's still in a very basic stage, but it's better than nothing!
I'm a HomeAssistant user, so I do want my TV connected to my network.
Now, the equipment that takes that display device and actually connects it to things like Netflix, Amazon Prime Video, Apple TV, etc.... that IS a device that I want connected to my network. It's called an Apple TV, and definitely is connected to my network. And it connects to the Samsung TV over HDMI.
I guess that would work as long as you move to a place far away from humanity. It definitely won't work if a neighbour runs a WiFi hotspot without password protection.
Advertisers or data brokers? They’re already subsidizing the purchase price of TVs.
I hear this claim a lot but have never actually found even a single one that does.
