Like many are saying, a lot of people seem to find their news elsewhere... To me, specialty magazines are more interesting in terms of getting News+.
Two issues I've encountered with it though:
My mom reads tons of magazine, which are all available on News+, but her iPad mini doesn't support the version of iOS needed to run it. I understand they want people to upgrade eventually, and to be on the latest iOS version, but for what she does with her iPad, she doesn't want to spend the money. They should have their services be more widely available, at least to older versions of their own software. (Take a page out of Apple TV+'s book, and that one is available on competing hardware, on top of some "older" Apple hardware (like my parent's Apple TV 3rd gen without an App Store))
Apple could loosen their grip on Family Sharing, or make it somewhat more flexible. My mom, my sister and I (all adults with our own credit cards) used to share a Texture membership. Doing so with Apple News+ (if it was available on my mom's and my sister's devices) would mean having one person with their credit card attached to the Family Sharing, and needing to approve other people's purchases, and managing getting reimbursed. (I know the other users can use gift cards to go around that, but it's not always practical... plus I live in the US and they are in Canada, so I don't even know if Family Sharing would work, with me being on the US store, and them on the Canadian one).
The way Disney+, Netflix and others are doing it is far simpler and more flexible. Even if there was just an equivalent of Family Sharing but just for subscription services (cause I understand they might not want to go that far with App, Music and Video purchases), the chances of us signing up for it would be much greater. As it stands, they'd want us to get 3 separate single-user memberships, but they are getting 0. They could, instead, get one Family membership for the three of us. Still better (financially ,for them) than nothing.
