> worrying that the generative technology could taint the final output with the creative imprint of another brand, while also expressing concerns about the potential use of their own intellectual property being used to train AI models.

Those reasons don’t seem that valid. Surely another brands creative imprint would be seen before publication and could equally be introduced from using 3rd party stock content or artists that have worked on other projects.

Not letting your ad agency use AI won’t stop your content being used to train other AI models either.
