Is Norton Bootable Recovery Tool really free to everyone?

Hello everybody, on this page the article say:

Norton Bootable Recovery Tool is a Rescue tool that is available for free to everyone.

 but reading other older threads and sites, it seems that you need a valid license for this rescue CD.

Now: since I am creating an USB rescue disk with multiple tools, and I wish to add NBRT without having a license, is it possible?

Or do I need a license?

Thank you
