You can legally download many specs from the ISO site, including the Open Document Format (ODF) specs. ISO lets you print out a copy. However, if you photocopy or scan it, or if you make it available on your organization’s LAN, the Copyright Police will haul you away.
I’ve seen similar restrictions elsewhere. They’re variations on the idea that you can download a document for free, but you can’t share it after you download it. It’s bizarre.
Maybe they’re trying to keep people from going into competition by selling copies of their standards. Since ISO also sells what it publishes, the goal would make sense. In fact, there’s a specific and emphatic prohibition on sales. But why they should care whether copies are printed or photocopied is beyond me.
Usually the answer to questions like these is “lawyers who are disconnected from reality.” If there’s a better answer, I’d love to hear it.
