#13 I hope this is one step closer to having PDF documents die in the most horrible twisted way possible, I hate it with every essence of my being.
Not for "green" reason but for bloat reasons and having the updater pop up at work which seems like every day.

#14Who wants to start a company? I just registered WWFtoPDF.com and WWF2PDF.com
I'd happily join you, but if I weren't already convinced the format will go nowhere, I'd assume it this whole campaign was a publicity stunt on the part of the WWF.

Uh don't use Adobe. Problem solved. "I hate Fords, when are we going to stop using cars."

#16Of all the silliness. There is already a "no printing" flag in PDF.

On OS X when you print to PDF you can adjust the security options to forbid printing.
(Um, not that I've made modified version of xpdf or anything… but I had a legal right to print that document and DMCA wasn't dreamt of yet.)

#17This is kind of a dumb idea, even on paper (pardon the pun). Deliberately crippling print functionality is a little gimmicky, despite the good intentions of the WWF.

#19I don't know if they got the memo that paper comes from sustainable tree farms that plant trees. Pretty sure Weyerhauser isn't flying down to South America to chop down virgin rainforests.
True, but it does create a lot of waste.

#20I downloaded the app and tried it out. They're saving files as regular PDFs with a .wwf extension. This causes the files to open in their app, but if you rename the file to .pdf you can open it in other PDF viewing apps just fine. They set a password on the PDF to restrict re-saving or printing.
Dumping the strings on their binary turns up genRandStringLength:, so I'm guessing they're generating a string of random characters and setting that as the password on the PDF.
They're just shipping a modified version of Skim (http://skim-app.sourceforge.net) embedded inside their own app to do the PDF viewing.
