I've heard the "blame a vendor" argument again and again in my life, but I have yet to see this "blame" ever occur. Granted, I'm dealing with small and medium-sized companies, but I've never seen any kind of tangible financial outcome from "blaming" a vendor (other than that vendor not getting future sales).
Not tangible financial outcome for the vendor. But for the employee suggesting it, who doesn't have to explain why "his" "cobbled together thing" doesn't work, but can point to all kinds of outside validation for the choice, even if it doesn't work out.
