The article clears that up pretty good and the subsequent twitter exchange someone posted Commercial via Directv is dead unless Directv makes a deal with the new providerThere are rumors that Directv will retain commercial or maybe even commercial + satellite residential rights via sublicense.
If say Apple got it and plans to charge $300, they could allow Directv to sell it for example for $350 and showing Apple's inserted ads or $400 and letting Directv insert their own ads. Not only would they make more than selling to those customers directly (so they wouldn't look at as a competition) they'd more money overall since they'd catch those customers who either can't stream or are older people who refuse to mess with newfangled technology like my mom (not an NFL fan, but she refuses to have anything to do with streaming even though she's got fast internet and a smart TV) Even if there were only 250K such residential satellite only customers that's $100M towards what they're paying.
Having Directv sell commercial rights makes too much sense. Every bar that wants to carry NFLST already has Directv, it isn't like there's an untapped market of bars that are set up for streaming on all their TVs but can't do satellite like there is in the residential market. Directv is already set up to do the billing and everything else, so let them handle the hassle and Apple can just cash the checks and worry about what they're good at - innovation on the consumer side.
No one knows what's going to happen until it is announced, so it is pointless to worry about who is going to be cut off from NFLST before then. It is in the interest of whoever buys the rights to maximize its potential distribution, since they will be paying the NFL a fixed cost.
