I think it's a matter of PR/optics, no matter how bad a situation may be Google are able to stay on message without coming across as untrustworthy idiots, whereas Facebook seem to only know how to make a bad PR situation worse. One recent example of this was how both companies handled the Apple enterprise certificate fiasco. Both companies admitted to using them for sketchy means (and both were knowingly taking the piss here) yet Facebook seemed to suggest that there was no issue with what they were doing whereas Google basically admitted fault right off the bat.
