A lot of people watch physical TVs, even if they don't watch "TV". This is about tracking what people are watching on the physical device, no matter the source.

A lot of people watch physical TVs, even if they don't watch "TV". This is about tracking what people are watching on the physical device, no matter the source. If I watch a Blu-ray or Netflix, my smart TV will still send a fingerprint of that content to their servers for analytics. As far as not connecting your TV you the Internet: (1) The default setup says you need to, so most people will since they want to watch Netflix. (2) There's so much free wifi around these days I wouldn't be surprised if TVs try to connect to any open wifi for "automatic updates".
