By the way SpaceX is my favourite company of all time. Elon Musk is living my 6 year old self's dream (actually my dream is still pretty similar, just haven't got their yet ;p )
// that is the exact line count from "wc -l" - I am not joking
I cannot help but look at the history of the big 3 Detroit automakers and their love of using service and support as a revenue source. It bit them pretty badly when Honda came along and made cars that didn't need the repairs.
I look at the example of the automakers every time someone tells me the proper business model for software is give away the program and charge for support, consulting, and training. I would much rather pay for software that I never have to call support about.
