As a very technologically savvy person, most TVs I have bought recently are "smart" TVs, just because that functionality happened to be included. I don't use it, but I imagine it's probably listening anyway.

This is the case for most non-technical people as well.

If I have a choice of a "smart" TV and a dumb one with the same panel, I pick the dumb one (it's also cheaper, but I'd probably pay extra). My "smart" TV in the living room would show ads on power-up until someone told me how to deactivate them. It still nags me to update its useless apps when I accidentally press the "internet" button on the remote.

I wasn't aware that airport displays like that are available to the public. Fascinating!
