Here’s the deal. The launch license is the agreement SpaceX struck with the FAA about how they would conduct the launch. This type of agreement comes about through negotiation, where the applicant (SpaceX) proposes how they will comply with the regulations to the REGULATOR (FAA), and the FAA provides comment then ultimately accepts or rejects the applicant’s proposal.
Once approved, the license forms a binding obligation on the part of the applicant on how they will conduct the launch.
So, something happened and SpaceX wanted changes to the license terms, (I’m guessing here, but likely proposed at the very last minute with insufficient time for the regulator to properly review and approve them before the scheduled launch).
At that point SpaceX made a business decision. Launch and face fines, or don’t launch and face cost overrun and delay. They decided fines and increased oversight was the better option to a delayed launch, and took the risk.
Now they are crying like a bunch of babies over the consequences of their decision.
SpaceX needs to grow up and own the consequences of their actions and quit whining about it.
