R. Jai Krishna, reporting on the reaction of Facebook Chief Operating Officer Sheryl Sandberg to the outcry over the company’s experiment on the emotions of nearly 700,000 unwitting users:

We take privacy and security at Facebook really seriously because that is something that allows people to share” opinions and emotions, Sandberg said.

The telling part about Sandberg’s reaction is that those who take privacy and security seriously don’t have to say it very often, if at all.
