>>9504801>>SpaceX developped the WHOLE Falcon architecture (F1,F9, FH, reuse, first dragon) from scratch for 2.5 billion,>spacex got more than 10 billion from the crs/crs2/ccdev contracts aloneNot true, and even if it were, those are mostly for services which cost SpaceX money to provide, and they get paid as work is done on them, not up front when the contract is signed.
For COTS they got about $0.5b for development, for CRS it's $1.6b for missions not development, CRS2 money hasn't started to come in and isn't public, CCDev is about $3.2b at maximum but over half of it is for missions, not for development, and the development money is for Crew Dragon (not the "first dragon").
>not to mention billions more in private investmentsThat's mostly for building their satellite business.
They haven't spent $10 billion on development. They haven't had it to spend.
