If you really need a smart TV in 2025, go get a dumb one, and then hook it up to a used nettop or a single-board computer like Raspberry Pi. You can use a cheap USB infrared receiver to control it via regular remote.

Install something like Plasma Bigscreen, and you’ll be golden.

This is why I have a dumb TV hooked up to a Linus htpc

Have a regular PC hooked up to the TV. That’s my smart machine. I control every aspect of it. Fuck Smart TVs.
