My dad's TV stopped getting updates, a bunch of the Apps slowly stopped working since then. If I were him I would feel ripped off every time I turned on the TV for spending extra to get a smart TV just to see a bunch of apps that don't work anymore.
Though getting spam on your TV and having it spy on you sounds worse.
I think the really winner is a cheap dumb TV with lots of inputs.
Only through hard work and perseverance can one truly suffer.
