This is typical drivel from someone who refuses to learn the lesson: "The problem is unscrupulous developers, hired guns. It could not possibly be me."

I wager the real problem is lack of oversight, lack of understanding of the problem being handed off to someone else, and lack of acceptance of ultimate responsibility for the mess.

So the title should be "Don't outsource if your intention is to not retain ownership in your project (Ownership as in understanding your project, the development process, and accepting responsibility for oversight the project's progress)"

Anyway...
