They could make tube tellies for peanuts given mass production. And I would suspect the same is true for LCDs, and even oleds given time. A rasp pi can be had for under £10. The packaging, manual, and remote becomes the expensive part. Not including r and d, support etc. But a move to open electronics/software could help here.

They have even ripped amps and speakers out of units, so they can monetize soundbars.

I had read that Google subsidized android devices, something like £30 a piece. So understand there is additional value in data sells. Edit: It may not have been android, but nokia's fork of Firefoxos on something like the banana phone.
