Most of the big TV manufacturers have significant privacy issues with their products. Texas just sued Samsung and forced them to limit what they were doing, which was pretty egregious.
Connecting a set to the Internet will always involve some invasion of privacy no matter how you do it.
Were it me, I’d pick up an Apple TV 4k box and use that to control the TV Internet content. Or, you could use an ONN streaming box or stick (they make them for Walmart) but I’ve seen too many of those 3rd party Android boxes that have turned out to have hidden malware to trust them. In the case of ONN, though, I’d worry less about malware but more about what Walmart might be tracking through it.
