Most definately NOT,because...
When all these expats joined,their terms and conditions stated "EXPAT CoS"...
The fact that they now have permanent HKID's is an arangement between them and the HKG government..it has sweet blow all to do with CX..
It's all about the conditions under which you joined..you know the deal,either like it or not..and then sign up or don't sign up...plain and simple..
