For anyone worried about the authenticity of digital content (and that should be everyone):
https://contentauthenticity.org/
I haven't read much about it yet, but at first glance it looks like a step in the right direction.
I have not read much about this particular initiative. But it seems to me its value is not so much about specific licenses themselves as about standardising machine-readable metadata, forming a coalition around it, and pushing for adoption end-to-end (from creation to edition to consumption). That seems cool and somewhat novel (and necessary!).
