My money’s on a joint venture with Comcast, Cox, Verizon, et al. to use the Wi-Fi access points their routers operate – even if you use your own router and block them, your neighbors almost certainly don’t. Most them already have business ties and would love to have better ad targeting data.
That's highly speculative, but even if that did end up happening, the smart TVs sold today wouldn't magically gain that capability, especially if you keep it off the network and never update it.
