Ok, this is going to start sounding like a flame war. I am not interested in flame wars. I will not continue to argue about this but here is my stake on the matter (again with no disrespect towards you solidsnake95).
Most of what you say about being "butthurt" because other people released hacks is, again, speculation. How do you know that he was hurt or even bothered at all. The promise of a release was, as far as I am concerned, never uttered by him. In fact, quite the opposite. He claimed that he would not be releasing it. He even explained that the message on 3dsbrew.org not to update was mainly for developers in the hacking community. If you had those expectations, it was not founded on Neimod's announcements.
Furthermore, I completely disagree with your use of "moral" obligation. a moral obligations requires that someone does the "right" thing because it is "good." The fact that you say he has a moral obligation highlights the fact that there is a bias in your opinion of him. You seem to think that his releasing an exploit is the "right" and "good" thing to do. Clearly your values are not the one's Neimod shares and he is thus not bound to your expectations. By your values, he might be "wrong" for doing this. But your values are not the de facto standard for everyone in the community. By your definition he was trolling. By his definition he might have been celebrating for all we know. You say he wanted attention, perhaps... but you have no evidence of this either. This is your perspective of it. If he did want attention, more power to him. Why does this bother you? doesn't everyone want attention in our day and age? We are, after all, emersed in a web 2.0 celebrity filled culture where everything we do should be publicized (hello facebook!). who isn't in seach of narcisstic attention these days...
Finally, the fact that he catalogued his findings on 3dsbrew.org is definitely useful for the community. I would highly doubt that other hackers, possibly even Gateway themeslves, never used any of it. Thus, it is useful in my book. Again, I do think that it is frustrating that he never released anything. but attacking Neimod for this (calling him a hypocrite, saying he was butthurt) seems rather too personal. Are we dissapointed in this... most of us would be. I, however, refuse to take it out on him mainly for the above reasons. I guess what I am trying to say is that we should allow for a diversity of views before taking it out on people. Just because our expectations are not met does not mean we should take it out of the very person that broke new ground. What he does with it is his own choice.
