In its latest latest 10-K (via Dealbook) Goldman Sachs (GS) writes:

“The financial crisis and the current political and public sentiment regarding financial institutions has resulted in a significant amount of adverse press coverage, as well as adverse statements or charges by regulators or elected officials.

“Press coverage and other public statements that assert some form of wrongdoing, regardless of the factual basis for the assertions being made, often results in some type of investigation by regulators, legislators and law enforcement officials, or in lawsuits."

In other words, pesky gadflies like anonymous bloggers, Rolling Stone critics, and New York Times journalists are hurting the company.
