Successful entrepreneurs do not "extract" wealth, nor is it given to them as some sort of reward for being great. They create the wealth. The compensation they receive is not given out of gratitude, it is agreed upon in advance if they succeed.

I and the D team makes and gives away D for free. Many individuals and companies have made a great deal of money from using D. They do not retroactively owe me money. I'm not upset that they made money off of D - I'm glad they did!

Of course it is nice when they decide to give back to the D community - I appreciate that. But nobody owes us anything for D.
