I am surprised the article doesn't citate any sources nor really has any information as to why the Korean App Store is requiring developer address details and then publicly displaying them. Seems like a very strange thing to do, but no doubt would be because of Government intervention or maybe it's a code-quality thing.
Probably because.. the author doesn't know..
This article seems to be pointing out something strange, not trying to explain it.
Probably local regulations related to operating in Korea.
