first of all, you are missing the entire point of the writers article, second, both games can coexist and thrive together, they cater different people and both can have their loyal fanbase, stop this mentality that this mmo will kill this mmo because, its false and stagnates the genre.

The article is about how unsafe are NCSoft games from NCSoft and partially explains the TR tragedy, NCSoft does not care about a games performance or even if it can sustain itself, it only cares about huge profit, so games are not judged in the merit of if they can sustain themselves, but on the merit of "if the money I give give more investment when in the bank or not".
This alone makes any and all NCSoft titles unsafe and impossible to predict, yes CoH might be thriving under players eyes and suddenly the plug be pulled just because NCSoft decided its better to put the money in the bank and collect investment instead.

That mentality will give short term money, but makes NCSofts reputation worse and worse.
