That wouldn't be the argument. They would argue that the form -- any variation of it -- is secret (or "sensitive security information") and should not appear on any website, anywhere.
What all these people seem unable to comprehend is that the form may justifiably be secret after it's completed with a passenger's confidential information, but the blank form can hardly be secret. The SSI notation at the bottom of the form undoubtedly refers to after completion, not before.
