I don't like these sorts of statements where people paint themselves as the victim of a situation, but won't explain what actually happened.
I think people should either be clear about what happened or stay quiet.
The bbc/production company could be absolutely in the wrong, or it could be something where he has declined a reasonable request as he doesn't agree with it for moral reasons
Eg. He has decided to become religious and doesn't think that working on a Sunday or wearing a skimpy costume aligns with his beliefs.
