If you’re still not clear on why it brings poor incentives, or you disagree, think about it this way:
For a company like Netflix, their customers are the people who use their service, and their product is their service. i.e. they’re selling how much you like their content. They don’t care about how long or addictively you watched it, as long as you pay every month. This is healthy.
For a company than runs a TV channel, their customers - for the most part - are advertisers, and their product is their viewers. They’re selling the viewership of their channel to companies. I.e. they’re selling how long and intently they can keep you watching their channel, and how easily they can get you to open your wallet. This is clearly unhealthy.
This applies heavily to the digital media environment too. I can give more examples, if it’d help
Some people do. I would like to see relevant ads (of good special offers especially) if somebody could guarantee the ads are going to be humble and unintrusive), the goods advertised are of high quality and no-scam, the information they get from tracking can not be seen by any 3rd party (including legal authorities) and used for any purpose other than good recommendations under any circumstances ever.
When I just finished school I didn't mind cookies (and actually hoped ads relevance was going to increase and increase) because I didn't think about the dangers which come with them.
There are people who still believe they have nothing to hide and don't mind relevant offers.
