I get that a lot of people invested a lot of time into this, but there's a suggestion in TFA that implies that this effort merits some special privileges, whether that inlcudes knowing the identity of the suicide or some other kind of recognition. It doesn't.
It was a voluntary act, perhaps a kind act, perhaps not from the perspective of the family. The implication is that the family either wanted to know or ought to have wanted to know. We have no information to evaluate those judgments, and there's enough gray there that it's irritating as an assumption.
The reality is that it is morally no different than participating in a subreddit on cats or submitting articles and commenting on them on HN. We're all voluntarily spending time on the internet rather than doing something else.
