I used to be an Apple Music fan, but Spotify just kept one-upping them in many ways (discovery, shared playlists, works well outside of Apple ecosystem) where I had to leave Apple Music. I'm not sure why anyone would pay for Apple News+, but perhaps there are enough News junkies out there that find it worth it. And in my household, there is at least one new Apple iPad, iPhone, Apple TV or Mac purchased every 12 months, so Apple TV+ will be consistently free.
I guess what I'm getting at is, unless Apple One is priced at 9.99 or lower, it's really not going to be a value proposition to most. I still wouldn't leave Spotify for Apple Music even if it meant Apple News+ for the same price.
