Broken Window Theory (Hong Kong version)

Why are so many broken windows in this group of buildings in Hung Hom?  

They include a hotel, office and residential buildings.  

All built by the same developer, in similar styles.

There are other hotels, office and residential buildings in the same area.  

None suffer such extensive damage.  

One obvious possible explanation is the (poor) quality of the glass used.   

These images have already become an icon of the (shoddy) business practices of some of the real estate developers in Hong Kong.
