I suppose it would take a seperate article to dig into the financial aspects—advertising and data collection as revenue for the manufacturers.
Yes, most consumers would buy a $250 TV rather than a seemingly-equivalent $450 TV, but another $200 just to not be tracked and advertised to is really a small lift. Kind of surprising that there aren't options for this in market if the numbers are really that tight. Compare a cheap Windows laptop to a macbook -- yes, they're not really equivalent from a technical standpoint but to a lot of consumers they may effectively be equivalent as the "device my kid needs for school." But the price differences there will be much greater. Perhaps as much as $500 or more.
3-5 years is smartphone life. New TVs should easily last 10 years. My $600 1080p TV from 2016 is still in the living room. A subsequent $600 4K TV bought in 2020 is also fine. I don’t see what could prompt me to replace them until they break. The quality difference is negligible, especially with the garbage bitrate most streaming services provide.
I'm just now starting to feel like I should consider a new one for the living room, but it's far from the top of my list.
Instead, they'll wait for the revolt, and then sell the upgrade. Then they look like heroes for doing what people are asking for, instead of villains that cause the situation in the first place. They'll spin it as offering affordable TVs to those can't afford them without the advertisements, and no-ad TVs for those who are willing to pay the extra.
And most people will eat it up.
The "Idiot Box" box qualification is not without reason.
