It is Apple news, because Apple is affilaited with Subway. We already know Subway includes Apple Pay. But because it includes Apple Pay, they are also show casing the expansions of the new kiosk and set up that is still correlated with Apple Pay and it's capabilities. Regardless, it is Apple related on how you view it, unless Apple Pay were not to exist, then neither would this article on the front page of Macrumors.
I don't understand what you are saying.
Last month: Apple Pay accepted in subway
Today: Apple Pay accepted in subway
The only difference is now you can use a non-apple-provided computer kiosk to order instead of talking to a "sandwich artist."
If subway gets new cash registers that still support Apple Pay is that also big Apple news?
