I hate smart TVs with a burning passion. They accomplish literally the bare minimum to keep people happy and sometimes not even that. Samsung’s Tizen OS is the most genuinely frustrating experience I’ve had with a consumer device outside of printing. Advertisements on my home screen that can’t be disabled, dubious privacy, bugs that require me to reboot my TV, and of course security so bad that they recommend install…
TV makers should stop embedding the Smart TV features, and focus on either bundling an external box on dongle, or establish a standard for smartTV circuit board that you can replace by a third-party or pull out completely when the inevitable happens (system is unsupported/EOL, has some security flaws the manufacturer doesn't take seriously, etc. And more importantly, make the display works without such card.
I've said it before here, but I'm getting a second hand NEC commercial display as my next TV. I've used them at work and they are excellent panels.
