I figured the password-protected files were made available in advance for the benefit of those teams who wouldn't have a quick internet connection readily available on the day of kickoff. That way they wouldn't be at a disadvantage because they were without official documentation while others had it in hand.

If it were my responsibility, I'd have provided an option to retrieve the whole .pdf collection in one password-protected (and presumably compressed) archive. That way it would have been a one-time process to extract the actual files using the password.
