Can someone explain what the guy's action accomplished? If you yank your code from the internet, and people have backups of it, and it was under the Apache license, it seems to me that people can just restore the code and keep working with it as if nothing happened. The license is perpetual, no? And that's not just a technicality - if FOSS licenses were revocable by the author at any time, only idiots would use FOSS in their business...
