> If no one wants to pay for it, it's unwanted. I'm sure you'd also want a mansion, butlers, a private jet, etc. for free. That you want something for free means nothing, and is entirely irrelevant.
The person you're replying to spoke directly to this by saying they want those services not merely for free, but for free with personalized ads. That is, by just saying "for free", you are removing an important part of the context. I suspect they would also sign up for a service that offered a mansion, butlers, a private jet, etc. for free with personalized ads, if anybody were offering such a thing.
I'm personally in the boat of preferring to pay for things that are important to me and hope to see more movement over time to subscription business models that work, but it does not make sense to write off people who want the opposite, who prefer to get things for free with personalized ads. The revealed preference in society seems to be that there are a lot more people who feel that way than people who prefer to pay for subscriptions. These people aren't just being duped, everybody knows how free services work because it is a very frequent and well publicized topic of conversation, it's just that they are ok or even happy with it.
I think what happens a lot, because I think it's what I experience personally very often, is that when we find ourselves with a minority opinion that we really think is right, that we conclude the majority with a different opinion from ours is just ignorant or being manipulated. But in reality, they are often just as knowledgeable as we are, but have simply drawn different conclusions. Speaking personally, this is always a bitter pill to swallow.
