This G+ post is a PR blunder. You should never apologize for something and then say that you are still gathering the facts about it. Second, you don't offer to sacrifice other people (while not yet having the facts). You either don't or you self sacrifice. Third, telling the public about an apology to someone else seems desperate. Just apologize. If there is actual public fervor, wait a few days and, like things your dog ate, news of the apology will come out from the other end. Finally, if you're a business with lots of money that other people want, it's probably best not to say anything. Get your lawyer to say it. That is what they are paid for.
And Google is evil. they track everything you do online, where your phone goes, and what you search for and sell that information, for fuck's sake.
Damned if you do, damned you don't - had they not mentioned it people would be pissed that they're so brazen as to think they can do something like this and just get away with it. As it is I like Google's personable way of taking early responsibility, even without all the details, just to let the concerned public know that they are aware of the issue and taking it seriously.
