All the more reason not to perpetuate a question on which the IP owner has a settled position. It wasn’t neutral.
I get that BBC has engaged an expert from the community, but in such a case the expert is under all the greater responsibility to ensure their neutrality. This isn’t presented as an opinion or perspective piece the way it might have been on the official site.
Had they written that there has been a long debate about TAS status, in part due to documentable statements by and those attributed to Roddenberry by his representative (I.e. Richard Arnold), and that there continues to be many fans that have reservations about its canonicity, that would be factual and neutral. This isn’t.
