Thing is, part of Googles identity is "don't be evil". A vital part of this is stopping whenever you (unintentionally) do something evil. This should not be a problem for Google at all or reason to loose trust in an employee. Unless, of cause, the company has changed. And that's what those story's area about and why we need them: To make sure the public image of google actually reflects what the company now actually is.
Btw: To those saying "why don't you just quit as protest"? For one that makes it easy to be dismissed as disgruntled ex-employee. But more important is the same reason you don't just leave your country of family whenever you disagree or have a problem with those. Cutting ties is a last resort that shouldn't be necessary.
I definitely don't. I definitely applaud efforts to improve things (relationships, companies, ...).
But going public ("airing your dirty laundry") is a kind of an ultimatum - "I have no other option to enforce what I want than to public shame" - and, while potentially effective, it's also damaging for the other party (and, ultimately, the "whistle-blower").
And at that point, it seems that the values are already so misaligned (whether the employee, or the company, changed is ultimately not relevant) that "divorce" seems like the only option. I definitely wouldn't want to stay in a relationship with someone if they intentionally hurt me (regardless if it was "my fault" or not).
Publicly badmouthing the company you work for is indeed sabotage.
