Actually, that's not true. ( least, not in the U.S.) In fact, if
I recall the story correctly, that's precisely what started everyone
slapping copyrights on their open-source software back in the early
BSD days -- somebody took a public-domain editor, made a few small
changes, copyrighted it, then started suing people who were still
distributing the original public-domain version for violating their
copyright! At which point, a bunch of outraged people who had been
dedicating their software to the public domain began using modified
BSD copyrights instead. [The GPL came quite a bit later...]
