^ As good a guess as any, Random. Assuming the OP is accessing FT for free? If so, then yes, I would assume as well that FT is controlling specifically what goes out in this manner.
FT ain't cheap so it makes sense I would think.
EDIT: I just tried FT and calibre NewsFetch using the free, registered account at FT. All I got were the news articles for US, UK, Asia and Middle East.
Nothing else.
So, OP, I can only assume you are using a free, registered account as well? Check the FT site - paid accounts have different privileges, one of which may be right for what you want.
