Dude I think we must be talking past each other or I am just not getting it, which isn’t all that unusual. Sorry.
Why not just say it was broken by this private company in the first place? Why did they take it up with Apple in public court, who had every commercial motive to justify not complying?

That was their Plan A.
The literally couldn't imagine any company operating in the United States would dare defy them.
When Apple didn't act like a good little Kapo *cough* soros *cough* they were stuck.
The rule of thumb for a lawyer in court is never ask a question you don't know the answer to.
The FBI assumed Apple would say 'yassa massa', or else. No muss, no fuss, and the FBI gets a back-door adaptable to any iPhone.
They were wrong.
Or I'm just not explaining it clearly (or I could even be wrong? Naaaah!)
Because according to people in the know, it took the private company over two months of work to find a way to do it. There were a couple of hundred similar companies working on it. Cellebrite was just the first one to get to the checkered flag with a workable, vetted solution that would stand up to forensic standards. It's not an easy thing to do.
