But there is absolutely no reason for you to hook it up to your home wifi. At least, until they are 'cloud'-enabled, and they require an internet connection to verify DRM before it plays ANY content... I shouldn't give them ideas.
My current one that I bought back in 2014 (or 13?) won't start up unless it thinks it has a network connection. I've actually setup my router to just block all traffic from it, but let it on the network so it'll actually work as a panel. Otherwise it has an unskippable menu demanding to be given the wifi password (or hooked up over ethernet).
A relative just bought a new TV this month, and asked me whether they should choose the "smart" TV or the normal one (I recommended the normal one, which they bought). So this is false, one can still find normal TVs.
