So they shouldn’t bother selling the TVs at all?
When they spend 400 on a tv and sell it for 410 and sell the data for 40 it doesn’t mean the data makes 4 times as much as the tv. The cost of gathering that data is still 400, they have nothing to sell without spending 409 in the hardware.
It seems conditions are such that the TV selling business is worthless (i.e. unprofitable) without collecting the data, and the TV data collection business can't work without selling TVs.
