In this age of lost privacy and identity theft, Adobe's security concerns are very real. There is no limit to the number of users trying to obtain credit card numbers and banking information through PDF forms being processed in non-secured servers and email attachments.
Yes it is a PIA, but having your identity stolen and miss used is even a bigger PIA in more ways then just the lost of money or credit.
I don't really follow your point. Your identity can't be stolen by the
ability to delete a local file. And while I agree that strict security is
important, it is also important for the user to be able to make an explicit
decision (ie to change the default setting) to lower the security
restrictions so that additional features will be available to developers.
And considering how strict Adobe is with regards to Acrobat, I'm still
amazed at this forum system, where people reply by email, revealing in their
signature their full contact details and other sensitive information for all
If a PDF could access the local operating system, the PDF could be scripted to copy your personal files, delete system critical or other files. or even change you system settings and possibly make your or your client's systems inoperable.
So can a Word macro, which is why you have different security settings in
Word, that the user can change globally, as well as a notification system
that allows you to disable macros for a specific file.
