AppleTV shows have started displaying ads for other shows before you can watch an episode. It is extremely irritating, considering that it's a paid service.

They're probably referring to in the App Store, perhaps Apple Music does as well?

e: Yeah looks like Apple Music, Apple News also, soon Apple Maps & Apple Podcasts

Just this week I saw a new ad on my iPad homescreen.

At some point an iOS update added a “Smart Stack” widget to my homescreen with some common app widgets (contacts, maps photos) (I assume it was automatically added, I don’t recall ever creating it, it seems to be a new iOS 14 feature.)

In iOS 15, iOS got something called “Widget Suggestions”, so apps you haven’t added to smart stack will automatically appear. (And this got automatically turned on for the smart stack on my home screen.)

Result: I got the App Store automatically suggested in my widget stack and displaying an ad for some Disney thing. (Which I assume I wouldn’t be able to access without either paying, or watching more ads.)

Wallet has a prominent un-dismissible ad for apple pay that sits above any actual items one might add to the app. IMO part of the overall trend towards tasteless and classless growth at any cost mindset from Apple.

Every address you accidentally click opens the App Store for Apple Maps, even if you only have Google Maps installed because Apple Maps has periodically sent you to the middle of a farm field (like it has for me).

The Music app's default screen is nothing but a list of ads for Apple's subscription services. I just switched to a third-party music app because I was tired of constantly getting that shoved in my face. The same subscription options are listed as first category in the settings app too.

News, AppleTV (the tv app, not the device), and the app store and Maps. The app store is understandable but I search for my very local bank’s app and at the top of the results was a big banner for a stupid app that had nothing to do with my local bank. It was like doing a Google search.
