Here's what I said about this on the official fora, with a couple of additions for things that have sparked discussion here:
[I quoted another player-attorney, who said, "That was an interesting article, but I think the lack of authority in support weakens its impact considerably. Really, it could have been written by a fan of the game and it appears that it was."]
I agree.
The author's analysis appears correct to me. For the most part, it's developed clearly. Even the tone, for the most part, is reasonable rather than blatantly hostile, something we haven't seen enough of in the past few days. It's a much better strategy to point out NCSoft's logical and business errors than to complain about how unjust its actions feel. I think there's been a bit too much inclination to treat the shutdown as an offense against whatever values one holds dear and not enough time spent characterizing it as a terrible business decision that hurt NCSoft more than it helped it. A business can ignore one customer's feelings, but it can't get around logic so easily.
However, reading from the point of view an uninvolved third party, my reaction was, "Where's the proof?" Even some of the statements for which support was available, such as statements about the amount of negative press, didn't have citations to that support. It may be partly my field (law) and sub-field (academics), but when I see assertions being made in every sentence, I expect every sentence to have a footnote citing some kind of supporting document.
The lack of documentary support (unfairly, in my view) calls the conclusions of the article into question. I don't expect it to influence anyone's analysis of the situation, which is unfortunate. Rather, I expect it to be written off by outsiders as the grumblings of a bitter fan. This isn't a fair or correct conclusion, but that's the one I expect.
In sum, while I'm mostly pleased with the article, and it certainly can't hurt the way things stand, I think players are exaggerating its impact. In particular, I caution players against treating the author's assertions about potential fraud suits as conclusive statements.
