We’ve reached the state where you can safely presume anything “smart” is violating your privacy.

Anything network connected.

Everyday we seem to step closer and closer to the 'network connected smart dust' as written in some science fiction.

yeah, I liked the simplicity of having things on my tv, but I gave up and got an apple tv box. I was getting way too many "I was just talking about that!" ads on some of the "free" services i was watching old tv shows and movies on. I'm a pretty frugal guy for the most part but buying a separate box that doesn't sell everything you do and say to advertisers is worth it.

According to the paper, your TV may send snapshots even when it’s in a “dumb” HDMI input mode. So make sure it’s not on the network at all.

yeah, to be on my home network you need a password. there are no "guest" networks. good point though
