Dji wanted their sensitive info (encryption keys) to be removed from Github. They issued DMCA claim, but it doesn't look like the claim was prepared with care; it stated a clear lie - that people who kept the Dji code published, did it themselves. In reality, these repos were cloned from Dji's owned public repos, which is allowed by Github TOS.
The well-known hacker who previously reported to DJI that these keys were published, filed a counterclaim - and now all the repos are re-instantiated. The whole situation made enough stir that many new people looked at the released data, and now we have a decryptor for Phantom 3 firmwares.
