There's no small amount of irony in the fact that attempting to open your .PDF without the comforting assurance of SSL gives me a "security warning" that I have to go out of my way to circumvent. I'm sure that it won't be long before it will simply become impossible for me to open the file "for my protection."

The push to mandate certificates and other gatekeeping mechanisms that enforce obsolescence for the sake of digital security theatre is ultimately going to benefit corporate bottom lines (especially those of landfill operators), but it will indisputably harm consumers.

I guess I should turn that into a comment and submit it...
