You are confusing two things, NASA outsourcing the parts built by other companies is a contract based project for which NASA was funded by the government. This means if any losses, are faced by NASA/government not the companies which made the parts.

SpaceX is more like a privately funded Space Exploration Company. NASA awarded them the contact not to outsource parts like in earlier projects but for SpaceX's design and technology.

Also the NASA contract to send cargo to ISS was one thing of the many SpaceX is doing. So in a lot of sense it is unique. Not sure why you think the ISS contract is the only thing what SpaceX is living on.
