Doesn't this violate the App Store guidelines?

> Section 3.1.3(b) Multiplatform Services:

> Apps that operate across multiple platforms may allow users to access content, subscriptions, or features they have acquired elsewhere, including consumable items in multi-platform games, provided those items are also available as in-app purchases within the app. You must not directly or indirectly target iOS users to use a purchasing method other than in-app purchase, and your general communications about other purchasing methods must not discourage use of in-app purchase.

To me, it sounds like Netflix is, "directly or indirectly target iOS users to use a purchasing method other than in-app purchase." I'm not saying they should or shouldn't break the rules, I'm just saying that they are.
