It is "worth it for some people" because those people don't understand how they're the product, how it influences what they see if they go on some homepage where their data is being used to manipulate their behaviour, how they lose money because of that manipulation, etc.
It will become worse now with LLMs feeding on their data. Soon it will be cheap to gather this data and use it for all kinds of scoring processes. All those things aim for gaining as much money as possible from those people who use services which seem _free_ to them but actually aren't.
Maybe at that point people will realise that they'd up paying less if they pay for those services....at which point they'll learn about the other cancer: which is companies which need to generate more profit every quarter and who make their services more and more expensive...and so on. #capitalism
I'm sure the tradeoff is worth it for some people, and not worth it for others. It's just not simple, and I don't know what the split looks like.
