As expected, shareholder efforts to rein in Mark Zuckerberg and company failed at Facebook’s annual meeting, where a plane carrying a banner that read “Break up Facebook, Save Silicon Valley” flew over Hotel Nia in Menlo Park on Thursday morning.

The night before, as shareholders arrived, they were greeted by a “Fire Zuck” projection on one side of the hotel.

This year, half of the eight shareholder proposals — all of which failed to pass Thursday — at the tech giant’s meeting called for changes at the top after numerous scandals. One proposal sought an independent chairman, aiming to limit the power of Facebook co-founder and CEO Zuckerberg, who is also the board’s chairman and holds nearly 60 percent of the company’s voting shares.

“We’re comfortable with our current operating arrangements,” lead independent director Sue Desmond-Hellman said Thursday in response to a question from Eli Kasargod-Staub, of shareholder advocacy group Majority Action, about whether she would be willing to call a meeting to elect a new board chair.

In an interview after the meeting, Kasargod-Staub said, “Her response is indicative of an abdication of responsibility by Facebook’s independent directors, and exemplifies the kind of irresponsible governance the company has demonstrated so far.”

The meeting’s audio was webcast, but the meeting itself was open only to shareholders. Kasargod-Staub described the mood among shareholders as “incredulous.”

When Zuckerberg was asked by Natasha Lamb of Arjuna Capital about having too much power, he responded by shifting the focus away from him and saying that one company should not have too much control over moderating speech, ensuring free elections and protecting online privacy worldwide.

“The question is: What is the right framework? Regulation?” Zuckerberg said. “We need industry bodies that will enable us to solve these specific issues that we’re grappling with.”

“Maybe he didn’t hear the question, but I think he didn’t want to answer the question directly,” said Jonas Kron, a senior vice president at Trillium Asset Management, which submitted the independent-chairman proposal, in an interview Thursday after the meeting.

Kron now awaits the final vote tally, which the company is supposed to file with the Securities and Exchange Commission within four business days. When Kron presented the proposal at the meeting, he said, “At its core, this shareholder proposal is about the risk of concentrating too much power in one person – any person.”

Afterward, he said he wanted to see what percentage of investors voted for the proposal for an independent chair.

“Is it 30 percent, 40 percent, 50 percent?” Kron asked. “Anything over 30 percent sends a compelling message to Zuckerberg and the rest of the board that it’s time to start a transition.”

Kasargod-Staub also said “elected officials and regulators will likely be very interested in how much support Zuckerberg has from his own shareholders” as they consider what to do about Facebook’s many issues.

Johnny Mathias, deputy senior campaign director for Color of Change, an advocacy group that has been talking with Facebook about its policies’ effects on black and minority users, said in an interview after the meeting that it was “somewhat galling to know that for a corporation larger than Christianity, there were 150 people in the room and decisions had already been made before anyone walked in.”

“What happens on Facebook is too important,” he added. “People cannot opt out, and regulators need to act.”

Facebook to halt new political ads just before U.S. election Zuckerberg wasn’t the only Facebook official in the hot seat. Institutional Shareholder Services, an influential group that advises shareholders on how to vote on corporate issues, urged investors to reject the renomination of Facebook Chief Operating Sheryl Sandberg and Marc Andreessen — who is on the committee that oversees risk — to the board. Glass, Lewis & Co., another advisory group, called on investors to reject Desmond-Hellmann over the company’s privacy problems. All board members up for nomination were re-elected Thursday.

Another shareholder proposal called for exploring strategic alternatives that includes breaking up Facebook, a refrain that has been echoed by co-founder Chris Hughes, Democratic presidential candidate Elizabeth Warren and others. Other investor proposals that failed: a call for equal voting rights, an effort to convert to majority voting for board directors, a push for a content governance report, and a request for a report on the company’s global median gender pay gap. Calls related to conservatives’ complaints that Facebook’s workplace and board are too liberal also did not get enough votes.

The banner-bearing plane was flown by Freedom from Facebook, which is urging the Federal Trade Commission to spin off WhatsApp, Instagram and Messenger from Facebook’s main platform.

The “Fire Zuck” projection, meanwhile, was courtesy of Fight for the Future, a digital rights advocacy group that has called for Zuckerberg to leave Facebook completely.
