Are you really do not understand a point here? It is about reaction to a rating, more freedom or better to say that authors need a possibility to leave the comment on the customer rating at least, no matter does customer left a comment with the rating rating or not.
If customer left 5 star rating without content author can’t react, leave comment. So what was your question please? Maybe language barrier I’m not sure. My English is bad too obviously when no one agree with me.
