A co-founder of Facebook called for the government to break up the tech giant in an op-ed article Thursday in The New York Times. “The Facebook that exists today is not the Facebook that we founded in 2004,” Chris Hughes, who started Facebook with Mark Zuckerberg in their Harvard dorm, told NBC News after the op-ed was published. “And the one that we have today I think is far too big. It's far too powerful. And most importantly, its CEO, Mark Zuckerberg, is not accountable,” Hughes said of his former business partner.
