PS: I think Odex has more grounds that what you write above just from the fact that they are actually going the legal route.
Frankly, from a bystander point of view, it is hard to argue the legal merits of the case, I would not do so as I am not a lawyer but I see many of you have already passed your judgements. The point I am making is from my personal opinon, I really applaud what Odex is trying to do.
As many of you has mentioned, it is really not in Odex best interest in doing it but this episode may bring hopefully iron out the copyright protection rights for other publishers so they can sue illegal downloaders more easily in the future. and do it in a LEGAL way in singapore.
