They are not entirely wrong. The person you replied to said "that country's citizenship":

> So a person who was born in the US and is therefore US citizen at birth will not be allowed to have that country's citizenship

Taking example of China, you said "the child is issued a Travel Document and treated as a citizen domestically"

"Treated as a citizen" is not same as "having Citizenship". OCI card holders are India are pretty much treated as citizens, except few rights such as the right of suffrage/ability to engage in agricultural land use etc, but that doesn't make them citizens of India.
