I like your idea of adding "SOPA would mean that we would have to black out portions of the Internet..." That would get attention.
As far as Google's advertisers, the G+ vs FB battle, and investors. It's either take a temporary stand now or get forced into taking a long term stand down later. What good is google ads if they can't run your ad? What good is a G+ vs FB battle if its really GOV vs G+ & FB? What good will it be to investors once their stock drops because google's ad rev (as well as other revenue sources) drops?
