Smart TVs replaced dumb TVs not out of consumer demand, but out of subsidy from commercial databrokers and streaming services. Despite adding $100 of hardware they were priced $100 cheaper.
The consumer demand was/is for cheaper, and data mining is how OEMs got there. The general public got what they want, and OEMs got to keep their margins: "win-win".
It's the same thing with (US?) airlines: people wanted cheaper, and that's what was offered and they chose.
