Every competitor in a new field simultaneously tries to maintain complete start-to-finish and top-to-bottom control of their niftiestness, and tries to become the standard to which all other competitors will have to comply.
VHS vs. Betamax? 19th century railroad gauge conflicts? Phillips vs. Pozidrive deck screws? JIC vs. SAE vs. DIN? Apple vs. Microsoft?
The plum to be plucked in some of these conflicts is government contracts. "MIL Spec" can be a golden ticket for a company, such as when Break-Free CLP met the "Un-meetable Spec" for a Pentagon-approved firearms lubricant.
Competition is a good thing. Open Sources is also a good thing -- giving rise to even more competition and creativity for after-products such as Androd apps.
But the .gov influence can get in the way of development, don't you think? I'm thinking of, say, how MIL-Spec ECWCS polar fleece stays expensive and crowds out development once it's THE spec.
