I can't speak for dmix, but some things that pop to my mind: Some companies have information security policies that certain types of data cannot be stored on (or sent through) servers in other countries. It's not about nationalism. It's about having it all under one legal jurisdiction (or limited set of jurisdictions). Having something like this self-hosted would be a great way to solve that problem vs using cloud services, (if it was verified not to phone home, leak data, update itself without permission, or allow remote access - hence why people want to see the source).
