I think it would be better to have some sort of link so that "if you are the copyright owner of infringing material and would like it removed, click here....". We shouldn't be making it difficult for people to get material they own removed from the history.
And in many cases we can quite easily remove material infringing someone's copyright from the page history, by using the selective undelete feature. The only problem area is where the copyright-infringing material has been incorporated into many revisions of an otherwise legitimate article since then.
