I laugh every time I see a livingroom with all furniture focused toward a fireplace. It truly reminds me how holdovers from out-of-touch lifestyles two+ generations ago still dominate some norms of interior decoration. Larger screens are objectively better in every way if you have the space.
Commercial "dumb" TV screens are available but are harder to find, and as I said, it's only recently that large computer LCDs (not TVs) have become available. But these are still not as large as recent gigantic smart TVs.
So when most people want a bigger screen, they see little choice but to accept telemetry. The more privacy-aware people take measures against it.
This is mostly because Roku/etc are subsidizing the cost of the device so far down the line that it becomes impossible to argue for the better ones, especially from companies like NEC/Sharp who make Damn Good displays for business.
