'The goal of the club was: “Give to help others"'

Why don't we see more companies with goals like this? The "avoid the negative" mottos are the popular thing in Silicon Valley these day (e.g. Google's "Don't be evil" and Facebook's "Don't be lame"). It seems to me that avoiding evil or lameness does very little to help you avoid other bad things.

A corporate motto like "Pay it Forward" or "Excite the Customer" or "Be Entrepreneurs" or "Hack for Good" seems like one that would benefit a company and the ecosystem it operates in much more.
