Also relevant is this line in the original DMCA email shown in the original issue:
> Otherwise, I will have to transfer information about you to lawyers who will cooperate with github.com and Chinese government to physically find you and stop the illegal use of licensed content.
The later comment I might have charitably excused as poor wording, but that line really highlights the threat being made. That this was in the original takedown letter just makes me even more worried about the business practices at Muse Group and its recent takeover of Audacity.
