That was a good listen. The previous episodes have largely been providing the context for this one, the one in which the big stuff that made the news happened. It provides an account from JKR about what led her to stand up and to make her first explicit gender critical tweet.
This is the the episode the critics were waiting for, JKR giving the condensed version of what happened. But had the series started here I think much would have been missing and in particular the useful context of why when JKR did decide to intervene it was into a atmosphere that was ready to explode.
What was especially satisfying to listen to is that in response to JKR setting out some reasonable fears, the incredibly misogynist and threatening tsunami of abuse made very clear that her fears were actually understated to a significant degree.
