The existing options for monitors, suitable for use as a TV, are extremely limited. For TVs 55" and 65" are common, for monitors there were just a few, which were dumb TVs basically. And then there are bigger sizes, different types of panels (there are no 4K QD-OLED monitors for example) that are not available for monitors. I think, if telemetry and ads are concern, buying TV without connecting it to the internet (using Apple TV or a homelab media server) is a better choice for many TV buyers.
