Until somebody releases a dumb TV, you just can't connect your tv to the Internet.

Even most cheap TVs now a days are 4k even if the panel is low end.
There is a large difference between 1080p and 4k which is usually quite noticeable if the TV is large but if it is a smaller size I can see how it would be less obvious.
I cannot tell the difference at normal viewing distances. Up close, sure.
This is how they get you to buy the 4K version, in the store you are standing 2 feet from the screen and you can see the pixels at 1080. Sitting at a normal viewing distance and 1080 looks great.
There is also of course the issue where people have bad internet (so netflix or whatever destroys the bit-rate, or they have the cheaper 1080p only plan... is that still a thing?) or old cable boxes plugged into 4k televisions.
There is a lot that people can do to inadvertently destroy their image quality without knowing which is not great.
Eventually every smart TV becomes dumb when they inevitably shut down the backend services.
Except that on newer tvs all the nagging will still be there, all the ads will be "frozen" in time (mine has ads for stuff from 2023, the last time I connected it for some firmware update that _GASPS_ actually fixed some things) and some features may depend on internet connectivity. The manufacturer may care to release a final update and solve these issues, but you know they are much more likely to fraudulently just disable features that worked offline as a last middle finger.
Repeat with me, SaaS is fraud. Proprietary digital platforms are fraud.
The things stopped working because they were for you the consumer.
The modern smart tv will keep working as long is its piping data back to the data retailers, they have a vested interest in keeping it going.
I do connect them to a jailed LAN so I can control them over the network.
