Because it is a 'smart Tv', and it asks to get connected to the internet during setup?

That being said, I have an old LG Tv (pre-android, forget what they call the os), and I never connected it, opting instead to hook up a firetv stick .... (who knows what bad crap they might be up to btw).

But the point is, we are a minority, most people go the path of least resistance.
