There exist numerous reasons to not love the idea of one's personal information, particularly regarding one's work or home, put out there broadly, particularly when it is attached to information one does not control and/or in a circumstance which would tend to show it to people who do not respect standard middle class norms of detachment. Redditors did not invent concern over this issue. Many of the people with strong concerns about it are demographically dissimilar to the modal Redditor.
Edit to add: It occasionally happens that journalists will transgress upon society's norms in this area and persons sympathetic to the aggrevied parties will transgress back. I have not heard a journalist say, in response to that "OK, fair commentary, wot wot." This often comes up in the context "We have published gun owners' addresses because the public has a right to know who owns guns." "We have published your address because the public has a right to know who writes newspapers."
I feel like I've read that story ~5 times over the years. First Googleable citation: http://www.nytimes.com/2013/01/07/nyregion/after-pinpointing...
Because that is what the comment to which I replied upthread claimed.
The fact that this guy on one hand built an incredibly high quality application that had and has a major positive impact on the world is a story that needs to be told.
The fact that he's a damaged, amoral man who is allegedly a career criminal and drug dealer is a story that demands to be told. He represents the Id of mankind -- and personifies the paradox that perfect security and privacy benefits society at large, and that society also includes the bad guys.
NB: I'm not claiming these rules are good or bad. But it's not like only freaks that are members of The Other have concerns about doxxing.
