Every TV does that unfortunately. It's called automatic content recognition but every manufacturer has a different euphemism for it.
It's definitely not just Samsung. As bad as this is. The problem is bigger than just them.
I have a projector that I just leave off the network. Do TVs require a network connection now? What happens when they don't have one?
ah so thats where microsoft got the idea for recall from.
Every TV might do this, not every single one does. Buy TVs which allow you to opt out (at least in one case it was several opt-ins, no opt out per SE).
