I agree with the article, but one thing makes me wonder. Initially one reason that developers are hesitant is because the difficulty of the project is underestimated. Layer, the author says to do it yourself, it isn't too difficult. This seems to be a bit of a contradiction. While I understand that easy is a relative term and agree that learning to code isn't too difficult, some may take that suggestion to mean that " if I can learn how to do it, your skills can't beer worth that much." Not everyone will think that, but some will. But I guess that's another clear warning sign not to work with them.
