I think so.
We don't hold copyright in works; we contract with authors who hold the copyright. It's our job to step out and make money with it. There are authors for whom we act, and we're always conscious of that. The question of income is, for us, so that we have to keep running our business and also so that we keep the cheques going for authors.
I think, to your question of whether it was equitable, yes. I think we were paid for use.
