From the point-of-view of the small entrepreneur, there is a world of difference between the advantages to the human race through the advance of science and the competetion of the free-market which, by its very nature, decrees that some business will succeed while others fail. Were that not the case, businesses large and small would not be investing in security systems designed to safeguard their proprietary information. You may consider that wrong; others generally do not disagree with one's right to protect intellectual property. such as the inordinate burden placed on extremely small suppliers and the consumer price increases which are the inevitable result of such a burden. What I was quite specifically cautioning against was the sharing of resources with the public-at-large (again, for the exact reasons I enumerated), not one-on-one with fellow members of the trade as a professional courtesy.
AK: After reading your reply, I'm not sure what you're trying to argue. On one hand, you're saying that what mmathew did was wrong because it might harm the business and then you try to argue that it might harm the consumer. Which one is it? What may be good for the business may not be in the best interests of the consumer? In the business world, the best product doesn't always end up winning. Look at Microsoft Windows with all its bugs and problems. If we're concerned about the consumer, then we should welcome the free flow of information. It's a straw man argument to say that it overwhelm the small suppliers. Why not let them decide? Some might welcome it as it would give them greater market share, and let them expand. If they don't want it, they could have changed their phone number and given it out to only those they wanted to do business with. And, I disagree that it would somehow destroy the magic. There are plenty of sources of textbooks that describes how to recreate a dish for chefs, how to perform magic, etc. in the public library where anybody can check them out. If you wanted to, one could even buy a medical textbook to learn the information that doctors know. But, that doesn't mean we've somehow lost respect the magic for these professionals.
