I guess the current consuming masses are just too dumb to use Preview anyway, Apple would rather want you to use their own Photos or Adobe Photoshop for images and Acrobat for PDFs.
Dumb people switching from Windows will only know one thing when it comes to PDFs:
Oh, by the way, did you know they dumbed down Preview even further on Yosemite by forcing users wanting to highlight certain images or texts using the Rectangle Annotation by slapping it right at the center of your previewing image and make additional tedious steps of resizing and repositioning it, instead of letting you draw a rectangle with just a single mouse movement on your intended target...? Just how stupid is that...?
Welcome to the dumbing down of OS X...!!!
Snow Leopard FTW...!!!
