Twitter has obtained a subpoena compelling GitHub to provide identifying information on a user who posted portions of Twitter's source code.

Twitter on Friday asked the US District Court for the Northern District of California to issue a subpoena to GitHub . A court clerk signed off on the subpoena yesterday.

GitHub user "FreeSpeechEnthusiast" posted Twitter source code in early January, shortly after Elon Musk bought Twitter and laid off thousands of workers. Twitter reportedly suspects the code leaker is one of its many ex-employees.
