Apple Vision Pro review: magic, until it’s not
(www.theverge.com)
This is a most excellent place for technology news and articles.
Apple TV+ and Apple Music do have first party status, subtly favored by the operating system itself. The Siri/search integration is tighter with those services than competing services, which is especially important on a TV interface (where there isn't a keyboard or mouse or touchscreen). I think search for music still only looks at the Apple Music catalog and won't search Spotify/YouTube/Tidal.
It's not a glaringly obvious promotion of their own products, but that's what I mean when I say that Apple pushes users towards their own stores. On desktop and mobile, they're pushing Apple's own paid cloud storage (and won't let competing services fulfill the same functionality), at the OS level.
