I have never had any smart TV complain (yet) that I have never once connected wifi. I am guessing there would be lawsuits, that a physical device requiring internet and requiring you to connect it just to function, would get sued in a class action of some kind. I use other connection systems via HDMI to transcode media, and even people who still want TV do not need to connect the TV itself to wifi, since it should all come over through HDMI ideally (or DP or whatever cables it may be.)
