MegaUpload was a site that people used to upload lots of data. There wasn't anyone upset by the PDF itself, but rather the other types of content on it. Examples, people were misusing a site like MegaUpload to upload whole copyrighted recent movies, illegally distributed software (I worked for one of those software companies that was victim.) and the like. The US government shutdown Megaupload some time ago. Again, the PDF was not the issue. I still have the PDF that I made of my book. Also, there is a site that someone else posted on this message board that had all the same content.
FG.
