Your point is generally valid, in that the price of selling advertisements and data is factored into the cost of TVs. But, in case you or anyone else despairs of buying a reasonably priced "dumb tv": you can still buy a 55" 4K TV with no spyware and no apps for $450 or less. For example, the Sceptre U558CV-UMC is $400 at that large online retailer from Seattle. I own the 65" version, and it's fantastic.
