Where each one falls short

  • The Additional Use Grant forbids offering Vagrant to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vagrant
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published
  • Uses that fall outside the Additional Use Grant require a separately negotiated licence from the licensor
