I think Sling just wants to offer as many options as they can. If I had to guess, Fox is probably the one withholding Fox News from Sling, because they seem to carry every other Fox channel. I also think to some extent Sling is not as big on News - they have it but most of it is in the News Extra package. I think Sling sees itself more as an entertainment and sports service, and then they also have news as a side item.
