I don't need 99% of software written in the world. Then I know 80% of everything is crap. Try to sell me something I will be polite but some people are not. I am tech guy but when I think of above I know I need salesman so he sell stuff that I build. Also you cannot scale sales infinitely so having middleman and getting 5% and not having middleman and getting 0 is win situation.
