Musicians algorithmically generate melodies, release them to public domain
Hackers have this idea that they can hack the law. However, judges are not computer programs blindly following the written instructions of the law. They are expected to apply "judgement" when resolving these cases, and they are likely to not be impressed by this effort. I suspect this will have the same effect as if a bunch of people got together and released a massive public domain dictionary and then claimed that authors could not bring copyright claims anymore because all the words they used were in the public domain dictionary.
