I disagree; this is non customer, non-financial data which is often considered fair game because downloading data is useful to locate many security bugs. Source code or config data is a prime target, but so is network diagrams etc.

Defense in depth means every defense needs to be validated not just the outer layers.

PS: Further, if FB says they know about a bug then anything he downloaded could easily be in the wild and should be investigated.
