FWIW, it is still possible to get TVs without this stuff, albeit at a premium. TVs are still made for business usage in areas like conference rooms, wall displays etc. They're often found under labeling like "commercial digital signage" or "business display" or the like, they seem to often try to avoid using "TV" (if being cynical maybe to make them harder for normal people to discover and confuse them if they do). But they're often nice panels aimed at serious running hours, without this sort of junk (which would give enterprise IT conniptions) and can have very useful feature support like 802.1x authentication which so many devices still lack. Players like NEC will even advertise their use of an RPi compute and wink at lack of spyware [0] for some of their products, but lots of major "smart TV" providers also have a commercial lineup.
I think they're well worth considering, particularly for the HN crowd, granted I suppose for people who truly want built-in netflix or the like without connecting something like a Roku or Apple TV maybe it's less optimal. But even they might change their tunes back to the concept of separate boxes and normal panels if they dislike all the ads and data tracking.
