I'm not sure the adtech is even enough to subsidize the price in a meaningful way.

Google’s global ad revenue equates to roughly $61 per user per year, most TV manufacturers would be unable to extract that much out per user, even with crazy levels of tracking, ads, etc.

I haven't used a modern TV in a very long time, but I can't imagine LG is extracting over $20 in ad revenue/data revenue per year. It might move the needle on <$500 displays, but when LG displays costing over $5,000 still have this spyware its hard to defend.

What makes you think LG would not be hitting the Google numbers (Instagram ad-free is ~$6 / month for example, roughly the same ballpark)? A device that's connected to a high speed internet connection, often allowed to do background tasks and being able to track all data being consumed through it (Streaming services, gaming etc.) is extremely valuable.
