As far as local pilots leaving CX in favour of HKA is concerned, that would only become an issue if significant numbers were involved. What that number might be, who knows? That said, your point about HKA being competition in more ways than one is valid.
So all that been said and accepted, it seems all the criticism and the thread "Demise of HKA" should now be withdrawn.
Too bad its open skies and more opportunities for employment in all fields and choices for passengers too!
No one need to play God either.
Good luck and happy landings!
