Offense or Defense?

Should Open-Source software go more on the offensive and point out any of the faults of proprietary software? Should a website be generated that continuously runs ads pointing out that proprietary software is less-customizable, less secure from virus threats, and doesn't want to be shared?

Hello and Goodbye!
