All of the iPad and Macbook charging bricks have been USB-C for a while, there is definitely a huge population of users that already have one. Plus, you know, it plugs into any usb-c port, it doesn’t have to be white. You can also get a standard Qi charger for what, $15?
Also, as the author points out (debunking their complaint immediately after issuing it, instead of simply removing the complaint from the article), you can use not only your previous iPhone's charger, but its cable (which obviously works with the charger).
