spies! everywhere!
honestly, as someone who cares about typography and culture in print, the constant and relentless "spies everywhere" statements from the security community look more and more like a sickness, not a defense. PDF was designed for print integrity, with images and typesetting, and I am grateful for it everyday. Please calm your alarmist content, and yes, security is necessary.. a good servant and a bad master, I would say.
