>so none of them have to do any of this stuff to survive
They aren't doing those things to survive but for extra profit. That said TV ads is the reason their prices have dropped so much and can block them by simply not connecting them to the internet. You still get a superior dumb monitor for their cost.
I mean you already here such arguments from smart TV makers and their fans as well as in other industries.
The real truth is all of this stuff would be fixed if a new standard and baseline was set for them so none of them have to do any of this stuff to survive. They'll find other ways to compete.
