As I understand it the source code is licensed MIT, the weights are licensed "weird proprietary license that doesn't explicitly grant you any rights and implicitly probably grants you some usage rights so long as you tell the listeners or have permission from the voice you cloned". Which, if you think the weights are copyright-able in the first place, makes them practically unusable for anything commercial/that you might get sued over because relying on a vague implicit license is definitely not a good idea.
