Early adopters to the Free Planet ideology, where you don't have to pay and pay and pay for life-basics like food, water, shelter, got this knowledge for FREE. People are beginning to see the sense of everything mankind can invent with his great brain being supplied by mankind, ethically-planet-friendly, for free.
"Do right by Free Planet," is the one and only rule.
The remainder of the seven billion people will now have to pay to receive this knowledge, think of it as a charitable donation or ransom (whichever you're more comfortable with).
