'Facebook is clearly aware that losing its chief security officer and dissolving its dedicated security team, in the middle of all that’s going on, is not a great look. So many of the company’s statements today are clearly designed to address obvious concerns that arise.
“We expect to be judged on what we do to protect people’s security, not whether we have someone with a certain title,” a spokesperson said. In another statement, Facebook said it is “investing heavily in security to address new types of threats” and that its new security structure has “helped us do more to keep people safe.”'

There is lot of misinformation about the Stamos debacle on all sides.
A true statement is that Facebook's security teams have been shifted around in several reorgs. A false statement is that Facebook has dissolved its security teams. The latter is a mischaracterization of the former, because while some security staff have left Facebook for a variety of reasons, the company is not deliberately reducing its security staff nor encouraging their departure. It still employs a huge number of engineers specializing in every major domain of information security.
If you'd like evidence that Facebook is expanding its security presence, you can take a look at its careers portal. It's aggressively hiring security staff in satellite offices that previously weren't focus areas for security engineering.
In my opinion, Alex Stamos' company memo gives a clearer picture of what's happened in Facebook's security org recently.[1] You should read that in addition to media reports.
