I'm starting to think that Google's unofficial slogan, "Do No Evil," is eventually going to cause them a PR problem (if it isn't already). So far Google has been fairly unblemished in terms of corporate vilification. Aside from a few clever jabs (such as this article from The Onion) and a brief outcry when people thought they were going to be reading user e-mail, most criticism hasn't yet entered mainstream consciousness. But as they grow in size and scope there will be more and more of it. And suddenly "Do No Evil" is going to become a constant pain.
Despite popular consensus, I believe most companies do NOT go into business in order to "do evil." During the late nineties the tech world was pretty much in agreement that Bill Gates was a bad person, even though just a few years earlier the tech world had loved Bill Gates for taking on IBM, the previous evil-company incarnate. The point is that when a company grows to a certain size, whether via a general distrust in corporations or some kind of laser-focused jealousy, regardless of that company's intentions, people start to suspect it of being secretly (or, in Microsoft's case, unsecretly) evil. And, like it or not, Google is at (or beyond) that point. They can no longer buy up other companies and release new free utilities and have everyone exclaim, "Google is the best! They have my best interests at heart!" Frankly, they've gotten away with that kind of response a lot longer than most.
When the tide changes, and the mainstream media and culture responds more cautiously (if not negatively) to new moves by Google (such as, perhaps, their latest push to not just own all your data but also all the documents you create) they are going to discover every single negative article and web comic and political cartoon poking fun at "Do No Evil." In fact, do a Google search on "Google do no evil" and after a couple of links to Google's corporate philosophy you'll find the rest are all questioning the motto.
Now, to be clear, I'm not claiming that Google is doing evil. I think they're just a company trying to grow and earn money by providing real value to consumers and being a good global citizen. But it doesn't matter if that's true, because big companies are seen as evil. So now Google has a choice to make:
1. Stick with the motto "Do No Evil" and have every critic constantly mock it and poke fun at it and question it and use it as a symbol of Google's supposed hypocrisy and call it a lie and essentially increase the level of general criticism every time Google does anything.
2. Drop the motto, which would be like admitting that they've decided to start doing evil.
