I’m not sure how to feel after reading this article, simply because I don’t think it offered enough data to make a reasoned conclusion. I think we can agree that industry monopolies are not a good thing. The question is, has SpaceX simply cracked the code to cheap launch or are they using monopolistic practices to squeeze out the competition (ie operating on a loss with the intent of bankrupting companies with less capital) ?
We don’t know what their internal launch costs are, so we can’t say for sure. However, it seems plausible that booster and fairing reuse has driven that cost down below the market value of launches.
