Angry Facebook shareholders challenge Zuckerberg over 'corporate dictatorship'

At annual meeting, investors condemn CEO's level of sway at the company, telling him: 'Emulate Washington, not Putin'

In the months since Facebook faced one of the greatest crises in its 14-year history over the Cambridge Analytica data scandal, its chief executive, Mark Zuckerberg, has faced tough questioning and increased scrutiny from his users, the media and governments around the world.

On Thursday, the billionaire executive faced another challenge: from angry shareholders at the company's annual meeting, where activist investors had forced votes on six proposals to change the company's governance or institute other reforms.
