You can't subscribe to Netflix and Spotify on the App Store anymore. It was possible for a while, where both just handed the costs down to customers. E.g. when Spotify costs 10$ on their site, it used to cost 13$ when purchased through Apple. I know Spotify stopped supporting in-app purchases when Apple Music came out, because even though both services are priced similarly, from within the Apple ecosystem it seemed that Spotify costs 30% more. And of course because of the anti-steering provisions for Apps, Spotify couldn't even tell iOS users that Spotify is cheaper when you visit their site.
