Companies reorganize themselves all the time, for better or worse. NCsoft will probably "reorganize" again when Blade & Soul and/or Wildstar are released. Put your tinfoil hats away.
You clearly have no clue whatsoever about businesses. Companies do not actually do this all the time. Companies do this when they *have* to.
NCsofts stocks are tanking and are steadily getting worse. They are doing everything they can to reverse this trend. Denying this would make YOU the tinfoil hat, because what I just said is pretty much basic company 101. Pretty much all decisions that NCsoft is doing right now have only one goal: Get their image back on track. Not the consumer image, of course (that one is tanking as well, none of the non-F2P game companies have that crappy an image, and that's saying something), I'm talking about the one to investors.
That is why they restructure. That is why they are doing several things across their entire portfolio to get positive press *among investors*.
Arenanet is likely just one company that is getting pressured into generating positive press.
This isn't even unusual. This happens every single time a company is taking as badly as NCsoft right now. They have to do this. Not because of Nexon, it's just because the other stock holders will demand it as well. Only an extreme tinfoil hatter would deny the existance of basic business strategies.
