Trollboy, down, down trollboy.
Fuck you too.
Allow me engage you in a little thought experiment:
Bah, semi-informed person who fell on TV commercial, imagining himself as a guy in a suit showing percentage pie charts. Go sell cars then!
Anyway, most of the late Microsoft offerings are open sourced as well. ASP.NET, MVC.NET, Web API.
No Office is not open sourced but who cares about that. And no, I don't think JS kiddos made lots of bug fixes for Apache server.
Most Opens Source projects like most of commercial projects boil down to a few really important people anyway. As for the channel for bug reporting and fixing its efficiency is mostly dependent on its organization. It can suck in the case of Open Source project and it can be great in the case of closed source one, and vice versa.
Now go sell the cars, you won't get multi-millionaire with that porn site.
