Any journalists running this sort of story are either unprofessional enough not to do the necessary research (and would likely not bother connecting the story to a press release) or, more likely, understand exactly what's happening but are just click whoring (in which case they'll just ignore it).

Timcook.blog.apple.com would have been quoted thirty seconds after the OP got put up - but it does not exist.
I can only surmise that apple does not reply directly because that sort of thing is not how apple works. Perhaps they should change.
