1. As far as I know, no one has presented any evidence that SpaceX sells Falcon 9/H launches for less than cost. ArianeSpace used to really talk up this point, but even they've mostly given up.
2. I'm not really sure why it matters. If SpaceX can sell for less than cost at their current volume, well... good for the tax payers - we're getting a deal.
> Elon loves to do this btw.
Really? I thought Tesla was known for it's high margins? I don't think any of Elon's other businesses are public.
