Having worked in this field, I can tell you how it usually operates: You want the most data for the least amount of investment. As soon as your operational costs start to eat into your already thin margins, the equation falls apart.
Complex solutions designed to capture data from that 1-3% of users who actively avoid it end up costing a lot more money than their data is actually worth. In order to make this particular solution work, you need to make enough money selling whatever tiny amount of data you get from those 1-3% of users to cover the cost of putting a cellular modem in all of your TVs plus the ongoing cost of paying various regional cellular networks to deliver that data to you. You are likely tripling or quadrupling the total cost of your data collection operation and all you have to show for it is a rounding error. And that is before we factor in the fact that these users likely aren’t using the built in streaming apps, so the quality of the data you get from them is below average.
