Interesting, but what about the situation where a new author adds his name as copyright holder without the consent of the original copyright holder, and with only one person making the decision whether or not this change is warranted: the new copyright holder? Doesn't this amount to giving the copyright away, or giving it away to everybody? GPL is often called copyleft for a reason: it basically cancels most of the rights that you would have with an ordinary copyright so that others can freely copy your work with no requirements other than that your copyright notice be retained, along with a potentially unlimited number of other "copyright" notices attached to the same work. (For completeness, there is a clause about not leaving misleading impressions about previous authors, but in my opinion the only way this could be enforced is if the contributions of the previous author are not altered. But this is inconsistent with the broad freedoms granted by the main text of the license.) The only "infringement" cases that I am aware of is where a company is sued because it tried to turn GPL software into a commercial product. This is what GPL was designed to do. It is not designed to protect authors (because that would be an attack on software freedom and apple pie, according to true believers).
