You make TVs that are spyware. Not just contain it, are. Their purpose is to collect data on the supposed owners that can be sold to advertisers (at least).
That doesn't let CR off the hook. Their "testing" and surveys have gone downhill a lot over time. At one time, they provided actual test results; now it's just dot summaries. For TVs, they appear to assume that everybody has cable or internet, so there's no need to even mention tuner (OTA) performance. They appear to assume that everybody has at least a soundbar if not a HT setup, so they don't even mention sound quality any more. And the surveys generally ask very generic questions.
Even so, they provide a useful data point. And for TVs, internet performance *is* an issue. Personal anecdote (with an old Panasonic plasma) - if I want to stream something, it works better to use the apps in the semi-old Samsung Bluray player connected to the TV than the TV itself, ON THE SAME INTERNET CONNECTION. So if people are complaining about hinky internets on the TVs, I can sympathize - only, to make the comment more useful, a survey question about the type of internet connection and possibly about whether any alternative connections such as a media player were tried (the latter, to focus on whether it's the wire or the TV) might have been informative.
