There's no specific reference in it to anyone. None of us actually know what happened but most of us also aren't desperate to jump to conclusions.

I did not see eye-to-eye with them. I didnít agree with the way things were being run. I didnít like the culture that had grown up around the series." If that later cocktail comment is about generic media people and not the specific
senior people of DW who he had a problem with then the quote makes absolutely no sense in the full context.
