But the decision to hold the meeting with the European Parliament behind closed doors has angered others. Shares in the company even rose after his appearance.
The data which got exposed was highly sensitive and revealed the personal details of Facebook users like their results of psychological tests.
We've reached out to Facebook to ask why Zuckerberg will not take European parliamentarians questions in a public hearing.
Yet the question of whether Zuckerberg should explain himself publicly remains a point of contention.
Zuckerberg will meet leaders behind closed doors, something that's being slammed by Liberal leader Guy Verhofstadt on Twitter.
Given Zuckerberg has thrice denied requests from United Kingdom lawmakers to take questions about his platform in a public hearing we can only assume the company made the CEO's appearance in front of European Union parliamentarians conditional on the meeting being closed. "It is a step in the right direction towards restoring confidence".
"Our citizens deserve a full and detailed explanation", he added.
The news comes a month after the parliament invited Zuckerberg to appear before three of the assembly's committees.
Zuckerberg has so far declined to appear, to the British lawmakers' annoyance. Ime Archibong, Vice president of product partnership at Facebook said, "We suspended the myPersonality app nearly a month ago because we believe that it may have violated Facebook's policies, We are now investigating the app, and if myPersonality refuses to cooperate or fails our audit, we will ban it".
