Earlier quoted context omitted.
It's a "dupe" if the topic posted today is the same as the topic that was posted a week ago. In this case, there is "significant new information" (or new/original analysis), so we can host a new discussion about it, as there are new things to comment on.
Thanks for some support but it's not a new analysis. The submitted Ars story today is from last week when the news broke. There was plenty of comments and additional links in the other discussion about this other side 'EU wifi' angle in that large discussion.
Who made you the judge? Just let HN do its thing.
