If you print a magazine you also don't get to recall all copies if you change your mind about something. Giving individuals this kind of control over other's ability to freely share information is dangerous because it is easily abused to hide information that is in the public's interest and that is not an edge case at all. Making a decision to publish something on the public web is hardly analogous to being caught naked even if you may come to regret either.

If anything, the IA should be more reluctant to remove information without a court decision.
