Mark Zuckerberg was not exaggerating when he described Sheryl Sandberg's imminent departure from the management of Facebook parent company Meta as the "end of an era".
Sandberg played a defining role in the success story of today's internet giant, and Zuckerberg owes her a lot.
She brought star qualities he never possessed, which raised the company's global profile and also helped defuse controversy, at least for a time.
In his eulogy to his long-term partner, Zuckerberg did not mention that the farewell had been in the offing for some time and was possibly even overdue.
In recent years, Sandberg has seemed to be moving more and more out of the company's center of power. Outside of the quarterly conferences with analysts, she has become less and less visible to the outside world.
Permanently in need of explanation
It was obvious for both sides to draw a line.
From Sandberg's point of view, her task has lost some of its luster.
She is constantly in need of explanations because the company is falling from one scandal to the next, and on top of that her influence is dwindling.
And for Meta, Sandberg is no longer the widely admired figurehead she once was, especially since she's played inglorious roles herself in a number of affairs.
It's certainly more dispensable for Zuckerberg today than it used to be.
Meta looks back on turbulent years.
The company that once had an innocent claim to bringing people together and giving them a voice has increasingly become a sinister force in the public eye.
It regularly finds itself in the midst of affairs, at times over privacy breaches, at others spreading misinformation, at times a lack of resolve in the fight against hate speech and other toxic content.
Meanwhile, antitrust authorities accuse him of abusing his market power.
Sandberg's reputation has suffered
While it is Zuckerberg who is primarily identified with negative headlines, Sandberg's reputation has also suffered.
She is considered the architect of the advertising business, which has made the company financially very successful, but also vulnerable to data protection scandals.
She must also be accused of downplaying harmful content on Metas platforms.
In addition to all the reputation worries, there are currently unfamiliar economic difficulties.
Meta's revenue growth has stalled and may soon come to a complete halt, and its market value has fallen dramatically this year.
This has to do with a generally gloomy environment, but there are also specific reasons.
The group, which until recently seemed so dominant, has become more vulnerable and is feeling the competition from other platforms such as Tiktok.
Meanwhile, Zuckerberg makes an expensive bet on the Metaverse, a futuristic new digital world whose economic potential for the company is still uncertain today.
After Sandberg's withdrawal, it is clearer than ever that Meta is the Zuckerberg group.
The co-founder is CEO and controls a majority of voting rights, so there has long been no question that he ultimately controls events.
At least Sandberg's presence gave the impression that he was part of a leadership team with two strong figures.
That will soon be a thing of the past.
