This is something people really shouldn’t worry about. Anonymity will always be a future option based on applications like this. That’s what fuels creativity. Aside from the fearful look. I think it’s relevant to have. Say if you need to find out where most people are particularly seeding a torrent. This may prove to be helpful perhaps someone will use umap in conjuction to find out where the mpaa/riaa people are. That would make it fair. If people are exposed so are the mpaa/riaa/etc.. would be awesome to see an icon pop up to see where mpaa/riaa are.
This would also prove that mpaa used that torrent to gain ip’s would also help in court for those who fall into the mpaa’s trap.
That being said umap no longer looks like a threat. It looks like a can of whoopass ready to be opened.
