Right but it would be easy enough to contact them to ask if they agree to use by the Morten group and a lot less time consuming than creating a whole new set of stories.There may also be issues with privacy/consent.
For example, I understand that the photos of people with ME, collected by MEA cannot be used by other organisations, as when they were supplied it was "for use by MEA".
It may be to use in their social media campaign to raise funds.
