What you call being naïve, I'd call being a good human being. Skilled professionals willing to freely share knowledge are a great thing. BTW., it's literally the foundation of our industry and the whole point of Open Source movement.

If it reduces market for some consultants, well, sucks to be them, they'd better find a different way of providing value. Not every value needs to be captured and priced. A world in which all value was captured and priced would really suck.
