Let's acknowledge everyone's contributions by replacing "Google LLC" in the copyright header by "The Jujutsu Authors". If I understand correctly, it won't have any legal effect, but maybe it still helps reduce concerns from contributors (though I haven't heard any concerns). Google employees can read about Google's policy at go/releasing/contributions#copyright.
