Troy points out in the article that it started as and has mostly entirely been a series of hacks done in free time, including a lot of done with not enough sleep on long distance plane flights. It sounds reasonable to assume that a lot of it is duct tape and straw wire and that the imposter syndrome "it's not good enough to open source" played some presumably large factor.
