Facebook held a meeting Tuesday for employees to ask questions about the Cambridge Analytica scandal.

But CEO Mark Zuckerberg and COO Sheryl Sandberg were MIA.

Some employees are taking to the anonymous chat app Blind to commiserate and discuss the situation.

As the latest news rages about how Facebook was exploited to manipulate voters by a company working for Donald Trump's presidential campaign and for the Brexit vote, frustration is growing within Facebook's employee ranks.

Facebook staffers want their CEO, Mark Zuckerberg, to speak up and defend the company. He has been noticeably absent on the issue. He hasn't posted on his own Facebook account. He didn't lead an internal company meeting that was held Tuesday. He has made no statements to the press. Ditto for the company's other famous executive, Sheryl Sandberg, who has also been radio silent on the matter.

This firestorm involves a whistle-blower from a company called Cambridge Analytica who said the firm took data from 50 million Facebook users under false pretenses to target voters with ads and misinformation.

Facebook says it was duped by the firm, which it said promised to delete the data after Facebook discovered its activities back in 2015.

Many Facebook employees understand and are on board with the company's defense. Plus they are used to news reports about some scandal or another at the company and believe that the news media can be overly dramatic or mischaracterize things.

"Everybody at Facebook in first year gets immunized to stories about Facebook — or they quit," one former Facebook employee told us. "But there are plenty of people irked about this, about Facebook's silence. They want Mark to go on TV."

'Is this how the downfall of Myspace happened?'

Many employees are also engaging in some dark humor about it. In the anonymous employee chat app Blind, one Facebook employee posted a message full of siren and fire emojis, saying, "Those are my thoughts."

Another employee called the situation "serious," but a third one joked, "Is this how the downfall of Myspace happened? I'm just trying to figure out how worried I should actually be." Blind makes sure the people using the app are employees by validating their work email addresses.

In fact, employees have also been active on Facebook's internal messaging groups, including one called "Wait What? Ask PR." Employees are going there to ask questions about Cambridge Analytica as well as Facebook's role in the 2016 US elections and Russian election interference.

"We have a very open culture at Facebook and welcome feedback through all of our internal channels," Vanessa Chan, Facebook's director of communications, told Business Insider.

The upshot is, employees want to believe, and do believe, their company's explanation that it is not complicit with any bad actors. But many don't understand why Zuckerberg and Sandberg are ghosts, allowing the world to believe that the people of Facebook are doing terrible things. As one former employee described, "Why are you guys letting us get grilled?"
