I'm thinking it's a mistake - the article indicates that SpaceX isn't in the mix at all (no mention)l. That's the mistake I see, and I think it's more likely the article (which makes for abysmal journalism) as opposed to the choice the Air Force has made (presuming that SpaceX bid for the contract) is abysmal.
EDIT: I'll leave what I've already written, but reading comprehension for the win (I fail). I see that SpaceX is listed right at the top of the article, and then isn't discussed further (presumably because they're so much better). And that makes sense.
It's true. The article isn't very clear because the procurement process isn't very clear. Basically, there was a "development" phase of money because the only company with a legal approved launch system is SpaceX. That development money of $2.3 billion went to ULA, NG, and BO. The asterisk on that money is continued funding of the development money will end when the two companies are chosen this year. ULA has the lead for the second spot with the Vulcan but BO and NG are fighting hard. This article is about how BO is making waves saying there should be a third provider to continue to get the development money for more development of a potential third launch system. I don't think NG needs to win this contract because they have a major contract to replace ICBMs but getting some development money is just second nature to the government contractor. The actual launch contract is coming up and SpaceX will be one of the two and ULA lobbyists will guarantee that ULA is the second. BO will argue hard that there should be a third and may get some concessions because the same thing happened to SpaceX on the last contract. That turned out to be a win in costs when SpaceX was allowed a few military launches.
