Netflix counts as a "Reader" app.

>>3.1.3(a) “Reader” Apps: Apps may allow a user to access previously purchased content or content subscriptions (specifically: magazines, newspapers, books, audio, music, video, access to professional databases, VoIP, cloud storage, and approved services such as classroom management apps), provided that you agree not to directly or indirectly target iOS users to use a purchasing method other than in-app purchase, and your general communications about other purchasing methods are not designed to discourage use of in-app purchase.

These categories seem arbitrary at best. Feels like they're more to justify letting big companies do X and force little guys to do Y (since audio/music/video subscriptions aren't really accessible to smaller companies).

VoIP apps? How is an email app any different? And Outlook for iOS has an Exchange client (and is aimed at people using Outlook online), but you can’t spin up Exchange in there. (I guess you could hook up Gmail to it too, but that’s not what they advertise it for).

So magazines, newspapers, books (written words) + databases and cloud storage are fine? But that sounds like the ingredients of EMAIL. So arbitrary.

I'm pretty sure you can sign up or sign in on the Netflix app.

I just signed out of my Netflix account on iOS. This is what I get:

>Trying to join Netflix?

>You can't sign up for Netflix in the app. We know it's a hassle. After you're a member, you can start watching in the app.

And yeah, obviously you can sign in.
