>Bonus: This way, you don't have to worry about open wifi networks.

I live near a BK, my TV could dl some auto auth for the wifi and just upload my habits... if it wasn't specifically chosen to reduce that probability.

How is it possible that your TV could automatically log into your wifi?

I believe they’re suggesting there is a public WiFi network in range of their home.

Where I live I can see a few dozen networks active. At any one time at least a few are public.

When purchasing a TV, this is getting more and more difficult. There’s few dumb displays out there these days.

I recently bought a TV and couldn’t find any dumb ones in the local big brand stores.

They exist, but not at the big stores. You need to find one targeted at a conference room, or factory. The factory is probably better because safety information is displayed on them so people can die if it doesn't work for some reason.
