Apple Vision Pro review: magic, until it’s not

This is a most excellent place for technology news and articles.
Apple TV+, the streaming service, does show ads for content. It's one of the worst, in my opinion, at pre-roll ads for other shows you didn't click on.
Then, in the interface, you'll get banner-like ads for other stuff, mostly Apple TV+ exclusives. Also, the interface also does push casual browsing (or search) into the paid buy/rent options also.
Apple's days of focusing on user experience above all else has shifted towards getting you to pay for stuff. Just because it mainly steers towards stores they own (app store, music/movies/TV, services subscriptions) doesn't make it any less intrusive of advertising.
Apple TV+ is an app though (which I never use). I'm talking about the operating system and the extended area above the apps is only applicable to the apps you put there (all of which for me just show the stuff you're currently watching).
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.
