The only reason TV’s are getting cheaper is the business model changed. Now your viewing data (and perhaps conversations) are part of their product offering.
I don't need the TV to be cheaper. I can afford to make up the difference for whatever few hundred dollars extra they would earn selling my data. But the expensive ones do this stuff, too.
This is just straight up false.
OLED productions costs have fallen, and the yields have gotten better — displays of all kinds have gotten cheaper, not just TVs; OLEDs have started showing up in products they haven’t before for cost reasons, etc.
The manufacturers make some profit on the data they harvest, sure; but the biggest BOM costs of TVs have definitely also dropped sharply.
