How is this connecting people's ID to their IP address when this does not involve anything to do with people's ID?

How did you manage to not only not read the article, but also fail to read the second highest top-level comment which points out exactly this?

This, by the way, is exactly why I think the comment I reply to should not have been made: it's contributing baseless suspicion and cynicism, and when other people read it, it arouses their suspicion, but without any remnant of whatever tenuousness may have been possessed by the original commenter. You aren't saying "I have a suspicion" you are saying "this is connecting..." as if you know it. But you don't know it - you haven't even read about what you're talking about.
