Chris Hughes says it’s time to break up Facebook: Is it feasible?

Facebook Inc critics who want the social-media giant broken up gained an unexpected ally in one of the company’s co-founders — but antitrust enforcers face long odds in taking that approach to rein in its dominance.

Chris Hughes, who founded Facebook with Mark Zuckerberg when they were students at Harvard University, argued in a column Thursday that the best way to curb the company’s power is by breaking it up, an approach that’s been floated by policy advocates and lawmakers, including U.S. presidential candidate Elizabeth Warren.

That authority rests with antitrust officials at the Federal Trade Commission and the Justice Department, who would have prove their case to a federal judge.
