just posted a great analogy between Linux and Enterprise Linux
This is no different from me buying groceries vs. buying an entree at a restaurant. Nothing stops me from buying all the ingredients of a meal I can order at a local restaurant. But nine times out of 10, I'm going to buy it at the restaurant, because I don't want to futz around with the "bits" myself. It's worth it to pay for the service. Is the service "proprietary?" Yes, in a sense, but not really.
Guess that makes us consultants caterers :)
