Why would you want to disable it? Even if you did, you could still download the PDF using other methods.

When viewing a PDF online, the user is able to save a copy to the hard drive by clicking the "Save As" button. There may very well be a way to disable this so that it is only viewable online, such as commonly done with streaming videos (think of it as a streaming document). There may be other ways of downloading the content, but having barriers can help reduce piracy.
