Isn't this sort of counter to open source and free software and the tools that many of us use daily? I mean half the tools we use are free and given away. Ruby, Linux, gcc, etc. What if the guys behind those projects never shared their ideas or gave things away for free? I mean it seems sort of hypocritical. I hope this doesn't come off as negative, but it just struck me that way.
