Some questions about using AppleNews+ including content and what publishers get out of it

I was thinking of trying AppleNews+ and had some questions.

1. I notice a lot of regional/city newspapers are included, like the Kansas City Star and the San Francisco Chronicle. How much do those publications earn in revenue? It seems like it could be a lifesaver in this day of dwindling separate subscriptions. It would be nice if the St. Louis Post Dispatch would also join and was curious what might be in it for them if the did.

2. Does the WSJ (Wall Street Journal) subscription include all their articles? I heard some people say yes and others say no. The question came up because the normal WSJ subscription is like $38/month just by itself.

3. If the publication has "article gifting" for subscribers, does that feature also work via AppleNews+?

The fact you can share subscriptions with family members is also interesting. Thanks.
