Pottermore used to have an interactive format with lots of original content from J.K. Rowling tightly structured around the Harry Potter books. In September 2015 the site was replaced with something resembling a mixture of Buzzfeed and HP Wiki. Much of the content wasn't transferred over.
So why did they switch over? Was the old site costing too much? Did someone up top think that what the fans want is clickbait articles that cannot distinguish between book canon and movie canon?
