It confuses me as well. Either many more HNers than I'd expect have subscriptions to these sites, or they're being wrongly bumped to the front page by HN's algorithms.

I submitted the article and it certainly wasn't paywalled for me. I wonder if the paywall is relying on geolocation or something.

I don't have any trouble reading it, and I sure don't have a Newsweek subscription.

Extrange, I can read it directly.
