Its maintainer stopped using it, and when it recently broke he started recommending a random fork from a user with no open-source presence that hasn’t made any update since. As for the live version, it’s now working thanks to some other random twitter user. The whole transition was a rush job.

I’m not saying those people aren’t trustworthy. What I am saying is that we don’t know, because the maintainer of DuckDuckGoog did not care enough to make sure the project would be left in good hands.
