Yes, I accept all the value that was generated by Linux is tangible and it's extreme.

I'm thinking from the principle of work: if you do some work for someone and it is not reimbursed, then it's obviously good for the people receiving your work but not necessarily the people working.

It's not the revenue from corporate UNIX that I'm thinking of, it's the being reimbursed for your work problem. The potential value produced by the non-free thing was destroyed.

Earning money is hard enough as it is, but today everyone expects everyone else to work for them for free, with nothing in return. If people stopped working on open source for free, would the value still be created?

To reiterate my point in my comment: if free things produce more value than commercial things, why isn't everything free?
