The most confusing part comes when I look at the Google Terms of Service. "The Google Services are made available for your personal, non-commercial use only. You may not use the Google Services to sell a product or service".
What does "non-commercial use" mean? The most concise definition I can find is "Non-commercial means that you are not getting compensated in any form for the products and/or services you develop..." (Intel® Software Development Products).
Is this the definition of non-commercial? "Non-commercial means that you are not getting compensated in any form for the products and/or services you develop. You cannot use the service to assist you to develop products and/or services that you are compensated for". This definition would mean I cannot use Google to search for programming references.
Perhaps non-commercial means, "you many not use this service to sell a product or service". By this definition employees of the company I work for cannot use Google Maps to sell our products or services. On the other hand, I can use Google Search to find programming references and tutorials.
