If you upload a PDF file to Google Docs and share it with other people, they can download it, print it and copy the file to their accounts. Now you can prevent other people from downloading the file from the Google Docs homepage: just right-click the file and select “Prevent viewers from downloading”.
For videos, this option is also available in the File menu, where you can uncheck “Viewers can download this file”.
While Google removes the download buttons and menu items from the user interface, there may be other ways to download the files.
