He calls for the breakup of Facebook, and increased oversight of the company and its CEO. Although Hughes hasn't worked at Facebook in more than a decade, he wrote in the Times that he felt “a sense of anger and responsibility” to bring awareness to what he sees as the social network's monopolistic tendencies. Hughes also writes that Zuckerberg's drive to win at all costs overshadowed the potential to cash out on Facebook early — as when he turned down a $1 billion acquisition offer in 2006, overruling the desire of both Hughes and Facebook's board of directors.

Domination meant domination, and the hustle was just too delicious.”Despite describing Zuckerberg as a “good, kind person,” Hughes slammed the CEO for prioritizing growth and revenue over concerns about user privacy and democratic influence.“I don't blame Mark for his quest for domination,” Hughes wrote. “He has demonstrated nothing more nefarious than the virtuous hustle of a talented entrepreneur. Yet he has created a leviathan that crowds out entrepreneurship and restricts consumer choice.”In response to Hughes' op-ed, Facebook executive Nick Clegg said in a statement that “calling for the breakup of a successful American company” isn't the way to hold Facebook accountable.“Facebook accepts that with success comes accountabiliy,” said Clegg, Facebook's vice president of global affairs and communications. “Accountabiliy of tech companies can only be achieved through the painstaking instroduction of new rules for the internet.”
