Re: SpaceX have turned rocket science into Spaghetti Engineering
There won't be a source, it's nonsense.
You only need to apply common sense. People are flocking to use the F9. SpaceX use the F9 for Starlink. Musk is not stupid and doesn't suffer from the "sunk cost fallacy". If it wasn't cheaper to reuse, they would not be reusing. And it's certainly cheaper than all the other providers.
As for the comment above about using solids. Just no. You cannot turn them off once lit. They are a dead end for manned spaceflight and more expensive than the Kerolox they use on the F9.
