How are you deciding what is "good" for a parrot?
A preference for humans is certainly not natural for a parrot. However, I don't think there's anything natural about the way most humans live their lives, and I quite like modern technology. Perhaps parrots similarly appreciate being in a safe environment with loving caretakers. (Or perhaps they don't—but I don't see how we could know either way.)
Put another way, I'm not convinced that living in the wilderness and having to scrounge for food and avoid predators is necessarily a better life than living with a loving human who cares for you. Both are certainly imperfect in different ways, but unfortunately we can't ask the parrots which one they would prefer.
