"However they are doing the same sorts of work as the bigger IT outsourcing operators and consultancies who never get questioned about their IR35 tax status. It is massive hypocrisy."
It certainly is. When IR35 was introduced (supposedly, I.e. we were told) it was to prevent companies (note, not individuals) doing exactly what the BBC have done, yet BBC presenters who have evidence that they were told work through a PSC or you're fired are getting hauled in to the courts and the BBC are sitting down with HMRC over tea and biscuits and discussing what to do.
Very glad to see that several MPs are very aggressively questioning both sides (HMRC and BBC) behaviour over that one.
