I believe there is an internet-enabled toothbrush, so why not? I refuse to buy a new TV as they are all internet-connected and ad-ready. There are a few offline ones or simple displays, but not so easy to find any more.
While the ad situation with modern TVs is not something I want to defend, most of them can still be used as offline displays if you forego the smart features and simply feed them HDMI video and audio data without ever granting the TV an online connection. Unfortunately offline displays tend to either be prohibitively expensive (becuase they are sold as business displays) or lag behind in the technology used.
