The article actually advises clients what questions to ask, and this advice is appropriate, because a client that is reading this kind of article in the first place is probably tech savvy enough to be involved in the development process. I've once even worked with a client with more actual technical and programming experience than we had, but they simply outsourced the work to us because they had too many concurrent projects and they also just moved up the food chain. Just dont try to do things by the "one-size-fits-all" mindset. Even having a legal guy to make very personalized and very different contracts for different clients is good if you can have it this way.
