I wondered that too. She's written 8 articles for Bloomberg and 7 of them are about Boeing - all in a positive light. Imagine she has the ear of Boeing PR.
Bloomberg is sort of a catch22 with musk. They try to highlight him as much as possible, even so far as to over praise him with really stupid matters. Then one little mistake or negativity, it is blown up and seriously investigated and written about.
It's not too surprising to see businessweek displaying a slight preference for Boeing over SpaceX, considering the former is public while the latter is private.
Investors do prefer public companies for obvious reasons.
