At the House Antitrust Subcommittee hearings this afternoon, Facebook CEO Mark Zuckerberg was directly questioned about his company’s strategy of copying competitors’ app and features, and even threatening to do so as a negotiation tactic amid M&A discussions. In his response, Zuckerberg was forced to admit the obvious: that Facebook, he said, has “certainly adapted features that others have led in.”

However, he denied any characterization claiming Facebook used such tactics in an anti-competitive way — for example, to pressure a company to sell to Facebook instead of trying to compete with it.
