It was a two-day interrogation with dozens of questions - some of them acute, some of them rambling, a few quite weird.
This week founder Mark Zuckerberg, whose account was one of those leaked, faced questions regarding data misuse in a two-day congressional hearing in the United States.
The stolen data was so widespread that it even swept up information on Facebook CEO Mark Zuckerberg.
Earlier this year, Mr Zuckerberg sold US$357 million worth of Facebook shares to fund his philanthropic organisation, the Chan Zuckerberg Initiative, after selling almost US$1 billion in stock last year.
After a long pause and an embarrassed grin he answered "umm.no!"
How much data does Facebook collect on users - and non-users? It was then people took note of the face Facebook was using their camera and microphone. Meanwhile, 35% claim to be using the social network less than they used to following the data breach.
Senate Gary Peters asked Mr Zuckerberg the direct question of "Yes or no, does Facebook use audio obtained from mobile devices to enrich personal information about users?" At the very least, we should expect some answers as to why Facebook has been able to get away with harvesting data from users that haven't consented, unless Zuckerberg continues to ideal the deflection techniques he's seemingly getting good at.
Others poured cold water on the idea that Cambridge Analytica was able to use these profiles as grist for its research on swaying voters by cracking the code of human intention. Any inquest into the activities of Cambridge Analytica or the Russian "troll factories" are easily disposed of.
'GET READY RUSSIA': Trump WARNS PUTIN 'Smart Missiles' Heading Towards Syria
Russian Federation denies its Syrian allies used chlorine or other agents in the Saturday attack that claimed dozens of lives. Konashenkov said Friday that Britain was "directly involved in the provocation", but didn't elaborate or provide evidence.
Remember that all of these "connections" are known by Facebook and owned by Facebook.
The university fired straight back.
But the data Facebook has on people who are not signed up to the social media giant also came under scrutiny. And as for Dr Kogan, the university had written to Facebook about its allegations against him but had not received a reply. "I have zero expectation that this Congress is going to make adequate changes".
The Centre, which is located in the Judge Business School, was drawn into the controversy when Facebook banned Cubeyou, another firm that had developed a personality quiz in collaboration with the university's academics.
Since the Cambridge Analytica scandal, there's been renewed attention to online privacy settings. The statement added that the Messenger apps would now "only upload to our servers the information needed to offer this feature-not broader data such as the time of calls". I wrote another article about that issue on Friday.
The data on Facebook users was gathered through a survey app on Facebook called "This Is Your Digital Life".
The email, from Facebook public policy manager Neil Potts, acknowledged that the company did not adequately communicate the new guidelines to Diamond and Silk and said that restrictions on their page would be lifted to allow them to apply to monetize their content.
