Which phenomenon? Being the author of an article? ;)

If you mean "why are names of companies being changed every couple of months?", I really have no idea, especially given that some of these companies seem to be linked, so it's not like different groups of people are doing it. Perhaps.

If you mean "why is the Hong Kong government making its Companies Registry less transparent over time?", there are some landmines involving China and tycoons that I'm not going to risk stepping on here, at least right now.
