If the contents are password-protected, decryption requires extensive
resources to break it. The PDF (Portable Document Format) itself is
just a format. Anyone that could figure it out (and without Adobe's
help) can create or modify it. PDF has always an open document
standard although getting the specifications for it wasn't easy or
maybe not even free.

That is why Adobe suing or threatening Microsoft who had added (but
then had to remove) PDF format when saving a file seemed so
ridiculous. Adobe submitted PDF to ISO as an open standard and then
only when Microsoft tried to use it did they then feel threatened yet
OpenOffice supports PDF. Maybe when the Macromedia folks (who are
used to proprietary Flash format) got acquired by Adobe that they
forgot PDF was an open standard. Adobe has freely provided the PDF
specification other companies; e.g., Apple's Mac OS X has built-in
support for reading and saving of PDF files.
In the wake of Adobe releasing the entire PDF specification (and doing
so in the past but often for specialized versions targeting a
particular usage), it really looks like Adobe can't figure their left
foot from their right foot in their threat of an antitrust lawsuit
against Microsoft (which Adobe wants to file in the EU since the EU
has repeatedly shown bias against Microsoft). Adobe says it is an
open standard, has submitted it to ISO as an open standard over a
decade ago, and now is afraid Microsoft is going to steal revenue away
from sales of Acrobat although Adobe has been providing the PDF spec
to other software vendors. Adobe starts with the correct letter "A"
for assholes. I hope XPS turns out to be Microsoft's PDF killer since
Adobe deserves it. For a blog that summarizes Adobe's attempt to
monopolize PDF (but only against Microsoft), read
