My first reaction is "we have no idea if the BBC actually did this for the stated reasons at all, or whether they are refusing to show it for some other reason and are blaming outside groups to deflect the blame and/or to make a political attack." My second reaction is "assuming the BBC is not just lying, do they have reason to think some groups would oppose it, or did they just magically come up with the idea? The only entity that this article names as objecting is the Telegraph. That doesn't seem like enough all by itself. Is there anyone else specific who objected? My third reaction is "assuming that that's true too, on what grounds did the groups object?" Neither the BBC nor the Grauniad gives any details about their objections. Just "it's right-wingers". The Telegraph link says that the episode was funded by political groups, and that doing so is not standard procedure--if so, this sounds like a completely reasonable objection.
