Personally I don't know what the exhibits in the Indian zoos were like during the late 80s/early 90s. Suspect that PZ didn't ask too many questions.
I assume the living conditions were somewhat lacking (or at least the husbandry was) as the vast majority of the apes died within the first three years of their arrival in India.
These are the Perth orangutan exports to India:

Bobby (sire of the Melbourne twins) was sent to Perth and then on to Hyderabad Zoo in 1986. He died at the Hyderabad Zoo in 1995 after being subject to 'malicious destruction.'
