Maybe it is copyright infringement, maybe it’s fair use. Either way it is unsurprising. When I got the physical paper it was easy to share it with a coworker (I just handed him the newspaper) or I taped it up in the office kitchen to show everyone, or I clipped an article and sent it to a friend (you know in an envelope with a stamp,) If it was time sensitive I could call someone and tell the to buy today’s paper... They didn’t have to subscribe to read one day’s paper, much less a single article. *For the record, I’m a paid WSJ subscriber.
