After Mr Zuckerberg rejected an invitation to give evidence to the committee and sent Mr Schroepfer in his place, Mr Collins warned that he could force the billionaire Facebook founder to attend by issuing a summons next time he is in the UK.
"If Mark Zuckerberg truly recognises the "seriousness" of these issues as they say they do, we would expect that he would want to appear in front of the Committeee and answer questions that are of concern not only to Parliament, but Facebook's tens of millions of users in this country". But the committee believes that these answers do not provide adequate detail and have called on the company for further explanation of certain issues. "Given that these were follow up questions to questions Mr Schroepfer previously failed to answer, we expected both detail and ata, and in a number of cases got excuses".
The UK Digital, Culture, Media and Sport Committee has been investigating allegations of misuse of user data surrounding Facebook's recent scandal relating to data analysis firm Cambridge Analytica.
The social media giant said in a blog post Monday that the suspensions resulted from its investigation into all apps that had access to large amounts of information before Facebook changed its platform policies in 2014.
Facebook blocked around 200 apps for interfering with user's privacy and misusing their data. It added that it had taken action against 370,000 apps in 2017.
The question over how many clicks or swipes it takes for users to change their privacy settings was also dodged. The meeting occurred last month, as part of the fallout of the Cambridge Analytica scandal.
Collins said that Cambridge Analytica was one of the areas where Facebook's response had been insufficiently detailed.
But it's also worth noting the way the MPs phrased some of these questions allowed Facebook this wiggle room - and opened up the avenue for debate on what a "real" answer would be.
Data such as phone numbers, private messages, and religious views, taken from as many as 87 million Facebook users and more than 311,000 in Australia, was allegedly used to influence voters in the 2016 United States election.
UK Parliament roars: Oi!
Mr Archibong said Facebook would "show people if they or their friends installed an app that misused data before 2015" at this website, but affected users would not be able to claw that information back.
There were a couple of new insights, such as detail on the extent of Facebook data gathering across the net.
MPs have again criticised Facebook for submitting "insufficient" evidence to a parliamentary inquiry about how it handles data.
