Whenever people say "free" in the context of information exchange, my belief is that they fundamentally misunderstand the nature of information. Information is a proxy for power, and the power comes from asymmetry. If everyone has a level playing field from an information access perspective, you cease to have functioning markets of exchange. The essential point of business is information arbitrage (I know something you don't know so I can buy low and sell high) and free access to information is antithetical to that view.
In short, everyone remembers the first half of that quote: "information wants to be free..." but conveniently forgets the second part: "... But information also wants to be expensive".
There is no "free exchange of information". It is always subsidized by the rich and powerful (no part of the internet's infrastructure is "free" and therefore any "free" exchange of information is a form of charity).
That is to say, it's hard for me to tell people to give up the information which is, in effect, their livelihood.
