All "open source" code was already pretty much public domain. All they'd have to do was put a page of OSI-approved licenses up on the site, right? An index of Open Source projects and their authors? Is this more than a weeks work to comply?

Free Software is the only place where this is a real abridgement of rights and intention, and it's over. They've already been trained on all of it, and no judge will tell them to stop, and no congressman will tell them to stop.
