I think it's that as well as the fact that they are a private company and don't do as much "contracting" in a sense. They aren't handed a gigantic set of legaleze requirements from the customer (the government).

Unless they do- I don't work there but it seems like they build their product, make sure it can lift X mass to orbit well, and if anyone needs shit lifted into orbit they just goto SpaceX. Far less bloat.
