Do you have any concrete examples where a third party library turned out to be the major factor of a project failing? I've done plenty of projects that rely on a large number of at least moderately popular open source components for example and I've never once had a major problem. Obviously all assumptions carry risk, you should have good contract terms etc. but from experience this element is not a high risk at all. Clients tend to understand the elements that are out of your control. Changing requirements is a vastly higher risk for example.
