Exactly. Imagine someone posting (anonymously) copy of EvilCorp's internal web pages, that prove EvilCorp is planning to produce bonsai kitten, as .pdf. If the pdf contains 'e:\nethome\joe_kitten_lover' .. then, well, Joe has a problem. (It would be bad if that .pdf contained username/hostname, too; I could imagine even timestamps being problematic.) (And yes, similar problems are elsewhere. Exif contains way too much information, if you try to leak pictures of bonsai kitten from digital camera.)
