Chief Executive Mark Zuckerberg said in a conference call with reporters that Facebook had not seen “any meaningful impact” on usage or ad sales since the scandal, although he added, “it’s not good” if people are unhappy with the company.
Zuckerberg told reporters that he accepted blame for the data leak, which has angered users, advertisers and lawmakers, while also saying he was still the right person to head the company he founded.
Please note that the issue was not a data leak.
1-None of what I just described involves ‘hacking’ Facebook or exploiting a bug. Instead, it all revolves around the use of a feature that Facebook provided to all developers and (at least) tens of thousands took advantage off.
2-The data collected was not internal Facebook data. It was data that developers accessed from the profiles of people who downloaded their apps (and their friends). Facebook has a lot more data on users than is publicly available and it has it for everyone who uses their platform. No-one but Facebook has access to that data. This is a point that almost all the journalists involved seem unable to grasp, instead they repeatedly equate ‘Facebook’s internal data’ to ‘data accessed from Facebook profiles using a third party app’. But these are VERY different things.
