The poster you're replying to is not claiming to be four different people or even any one of them, and your challenge does not contribute anything. In the case of Lee Kuan Yew, he did indeed drop Harry from his name, with varying stated reasons.

The fragment "Hated the name Harry and got it removed" probably means "[He] hated the name Harry and got it removed", not "[I] hated the name Harry and got it removed". The grammar is acceptable in many contexts.
