Despite perhaps not being the only reason, the most obvious reason is that the US wants to be the only country to possess F-22  technology.

Summary

KEY POINTS:
  • With so many potentially sensitive technologies in the F-22, the US won’t even allow a stripped-down ‘export’ variant.
  • There are likely aspects of the F-22 that no other country has replicated.
  • The F-22 program was cut short, so production processes may not have been sufficiently established to support foreign variants.
