If I was a business I would avoid low hanging fruits in favor or more risky ventures that are perhaps less likely to succeed or yield profit. Businesses are in the business of business, not in the business of tacking hard problems just to spite the rest of the world. I think the image of Google being this almighty good intentioned soul is over blown because at the end of the day they answer to share holders, they profit of advertisement and the rest of it is ice cream that goes on their advertisement cake. I love google for the services they provide me but I also am not naive that a business is going got be a business first and a good hearted soul last.
