Thing is, PDF is a printing-oriented format. It is a close descendent of PostScript, a full-fledged programming language, but geared towards printers. The main point that makes PDF a more convenient format is that Acrobat made a big campaign to distribute its PDF reader program. As you quote, others have told you the PDF-provided security is fake. It is just a flag flipped to tell the reader program to pretty please make life miserable for the user. What do you want to achieve with this _real_ protection you say? Whatever can be displayed on screen can be captured (i.e. with the common "PrtScr" keybinding in many environments). If you want to distribute material and make it hellish to your users to print it, copy from it or use it in any useful way, why don't you send the document as a .jpg file?
