Zuckerberg spends the first part of his response running through the events as we know them, and by now they're fairly well understood - a Cambridge researcher created a personality quiz that was taken by around 300,000 people, but because of the way Facebook's Friend APIs worked at the time, those 300,000 people inadvertently also handed over information about the people in their own social networks.

Questions are also being raised about Cambridge Analytica's role in Britain's vote to leave the European Union in 2016.
However, the academic who provided the data disputed that on Wednesday.
The Cambridge Analytica scandal serves as a forceful reminder that there are consequences to posting on social media.

So as the Cambridge Analytica scandal passes its crescendo, just get ready for what's next, because we as a society will need to have some really tough conversations about what we share online, who can access that information, and, most important, how we can protect ourselves. Critics believe that it essentially was a breach because information of undoubted friends was taken.
