I read one thing loud and clear from this statement: Facebook is not prepared to take the blame for what has happened.
Contrition has never been Mr Zuckerberg's strong point, and this statement, days in the making, is no different.
No apology to users, investors or staff over how this incident was allowed to happen by the data policies in place at the time.
No explanation as to why, after learning its data was being abused like this in 2014, it opted to give the companies a telling off instead of banning them outright.
No reasoning as to why Facebook failed to inform users their data may have been affected. Technically, it still hasn't.
Mr Zuckerberg's words were not an explanation, but a legal and political defence. This company knows it is heading into battle on multiple fronts.
