Your point about a smartphone's capabilities is well taken. But the TV straight-up says that your personal information will be captured and transmitted to a third party.
I value my privacy, and trust (hope?) that my phone isn't transmitting that sort of stuff. If it did, I think it would be discovered and made public very quickly, and I would switch phones! But since the TV straight out says that it transmits my personal information, and I have no reason to doubt it, I'll be sure to not use that TV, or at least not connect it to the Internet.
We can trust others to safeguard our privacy, as a sort of calculated risk. But this TV is just saying out loud that it won't do that, so I'll avoid that model.
