Commercial providers for space programs cost more money than if NASA just hired civil servants to do a lot of the work. Big corps just take longer, then don't want to share development info that taxpayers funded, making integration into other elements a huge safety problem that can't be fully resolved due to the protection of the provider's intellectual property.

Then they get shit workers that put up with job instability caused by a fickle Congress. This has gotten progressively worse for decades, and now NASA is reduced to a corporate subsidy program for parasitic billionaires and huge companies that don't deliver well. Nothing like someone asking me if a design will function properly with another, and me basically saying I have no fucking clue because everything is a goddamn secret.

NASA's commercial provider obsession was bought by lobbyists, and it's a fucking terrible idea. I'll die on that hill.
