Elon Musk said 5% of SpaceX was working on Starship and that the hardware for crew would be ready this year (in interview to CNN after the QA he said October for in flight abort and November for DM-2).
Almost certainly the top minds at spacex are focussed on starship, and the 5% number might only be kinda-true because starship is being built with a lot of contractors.
Well when you tell a customer you will have all hands on deck and then are out back playing with your go-kart then expect your billion dollar customer will say something.
I imagine all the necessary hands are already on deck for Crew Dragon.
Starship wasn’t built by the Falcon or Crew Dragon manufacturing teams, and the vast majority of the design and engineering currently happening for Starship has long been completed for Crew Dragon.
Let’s also remember that NASA is hardly the only company that pays SpaceX, they have other income sources and what they do with that income is ultimately their choice. Unless they are using NASA money to build Starship there should be no problem.
"Musk said in 2018 that SpaceX was “all hands on deck for Crew Dragon,” and it would be making trips to the ISS by December 2018.
After that, he said, “most of our engineering resources will be dedicated to BFR, and I think that will make things go quite quickly,” he said. BFR was the earlier name for Starship."
"All hands on deck" is not some subjective term, it is naval and means get everyone on deck now to repel boarders.
Except there is nothing they can do now. There are a ton of safety reviews which depend on NASA, and only a small amount of people at SpaceX are required to keep the NASA team more than filled with work.
Elon responded saying he would do whatever it took to go faster, but there was nothing he could do.
