But, I do worry that we have a whole generation of people who think that stuff should just exist and have no monetary value like it just materialized out of thin air without anyone working on it before and neither having to keep it running. That is not a healthy mental model and it will contribute to predatory companies being able to harvest data out of these people in the future

I see where you are coming from there, and I don't disagree with your opinion, but I do still think that while that may objectively be a mindset that is potentially harmful, I feel the net impact in this context is more likely to be increased contribution to and support of things that really are Free (gratis and libre), nudging reality closer to a place where a lot of those sorts of services are free or donation-supported, and less likely to be in corporate hands unless those corporations improve their behavior.

A hard to summarize version of that sort of path and mindset is what initially pushed me away from Windows, but over more than a decade I've developed lots more reasons than cost for why I'd never go back, and for why I've become a Free Software enthusiast and advocate.
