I read this article, and there was nothing like a "smear campaign against george soros" happening at all.
There were no "attacks" on soros.
Facebook … hired … firm "to discredit anti-Facebook protesters by linking them to figures like Soros,"
I don't see how that's an attack on Soros. If everyone thinks that Soros is the devil, it's an attack on anti Facebook protesters to compare them or link them to the devil. Nobody knows anything about the AF protesters, it's not really a negative to be linked to them. And everybody knows Soros and most hate Soros, so, it's not an attack on Soros to link him to AF protesters.
