So your TV just connects to random wifi networks? That sounds a bit insane.

It doesn't sound insane, actually. Keeping in mind, Windows XP did exactly that for a while until everyone realized, "hey, that's a security issue". I would swear MacOS too, but I wouldn't bet money on it.

That example isn't a random wifi network, it's the Xfinity network.

But also, you think tv manufacturers are sane? They have proven that they don't deserve the benefit of the doubt, in my opinion.
