Just own up to it but there is a lot more to it than that in some cases. It comes down to being honest and living up what you say your stated goals are and how your actions reflect that or how the market or customer base perceives that you are living up to them.
If you love Google and everything they do and own their stock, then you're going to love opinions like this and probably think they are really in touch with you and your goals are aligned with theirs.
If you think "Do No Evil" is lip service, then something like this comes out and strengthens your belief. Then they come out and say oops, we shouldn't have said what we think or what someone here thinks, it probably strengthens your belief even more that its about PR more than honesty.
It also depends on how the actions of a company affect the customers in the marketplace. Take Dell and their troubles lately with motherboards and customer service. It's a PITA to deal with those things & maybe you've had issues with Vista too. Then they come out with this about Vista & XP [webmasterworld.com] and though you may had had issues with them in the past, taking this stand acknowledges that while they might have had or still have issues, they are listening to the marketplace and despite their business relationship Microsoft, they are willing to acknowledge and address an issue that their customers may face and customers may feel good about that. In Dells case an action can help to correct the problem because the problem and perception is really tied to the product. How about Google?
