What is not fair is expecting that every single person is a possible customer, and if that person hasnt passed you money, you deny him something that cost you nothing to reproduce (notice i didnt say 'nothing to produce', my issue is with trying to license 7 billion people).
The business model of making something and expecting infinite licensing needs to die, NOW. IP is not real, and should be discarded as we move into the Information Age. Find new business models, stop restricting thought for profit. Provide a better SERVICE.
