No, no they didn't. They inherited the machine, or bought it from someone else. This isn't software engineering, where people bootstrap their compilers. They signed exclusive contracts with suppliers. They designed parts which took many iterations of surface finishes and annealing schedules and tolerances to get right. Each iteration requires months of turnaround time and $€£ in manufacturing costs. Sure the team can go elsewhere. But it will take them almost as long to set it up the second time around, and almost as much money.
