No, this is just one of many reasons I haven't yet bought a smart TV. I probably will give in this year, but only because I can finally afford something much larger than what I have today.
Here's the thing: At the end of the day, a smart TV has capabilities that I don't need or want, including to change how it functions without warning or consent. However unlikely the possibility is, a smart TV still has the capability to connect to an open network, phone home, and start doing shit I don't want, which means I have to trust it to not do that.
On the other hand, my old dumb TV has none of those capabilities, so I can trust it precisely because I don't need to trust it. I know it can't do anything except display what it receives on its inputs.
Therefore, any time I've considered replacing my TV with a newer one, I've always weighed predictability against uncertainty and opted in favor of the predictability of what I own.
Maybe that's overly paranoid of me, but at the end of the day, I just haven't wanted a new TV as much as I've wanted something I can trust.
