I posted about this, and in detail about my experiences with Apple, trying to get them to unpin certain political topics that were being pushed to me against my will, and was silenced by the moderator. This issue is more serious than it seems. It seems designed in a way that you can pick your areas of interest and publications (but only from the narrow assortment available,) but Apple will send you what it wants anyway. Either that is a failure of programming (utter incompetence) or it is by design.
