I think that the difference here is that Google, publicly at least, says lots of the right things about privacy. They seem (again publicly) at least genuinely concerned about privacy. Whereas FB (and Zuckerberg in particular) has made many public statements about how annoying people's privacy is. That's why I think Google's apology is coming from a sincere place, and the mistake was simply driven by an abundance of ambition and a lack of caution (cause by hopeless naivete). FB's apologies always rang hollow because we know Zuckerberg is tremendously aware of the issues (because he's informed of them in nearly every interview) and simply doesn't care.
