Dear Mr. Nathan Freitas,
It has come to my attention that you have made an unauthorized use of my copyrighted work entitled obfs4proxy (the "Work") in the preparation of a work derived therefrom. I have reserved all rights in the Work, which was first published on 2014.
Your work entitled Orbot, which appears as a binary distribution available on the Google Play store and F-Droid contains a copy of the Work, without including copies of the Work's copyright notice, conditions, and disclaimer as set out in the Work's software license.
Therefore, I believe you have willfully infringed my rights under 17 U.S.C. Section 101 et seq. and could be liable for statutory damages as high as $150,000 as set forth in Section 504(c)(2) therein.
I demand that you either comply with the terms set forth in the Work's software LICENSE, or immediately cease the use and distribution of all infringing works derived from the Work, and all copies, including electronic copies, of same. And furthermore that you desist from this or any other infringement of my rights in the future.
If I have not received an affirmative response from you by October 17th, 2017 indicating that you have fully complied with these requirements, I shall consider taking any and all legal remedies available to rectify this situation at any time without further notice to you. This letter is without prejudice to my rights and claims, which are expressly reserved.
Sincerely yours,
Yawning Angel
