> Apple's guidelines are meant to be broken anyway. Bloomberg's app (Bloomberg Professional) is unusable without an account, which is 100% against iOS guidelines

Any app whose purpose is to allow users to access subscription content works this way.

Netflix would be another common example of an app that is used to access subscription content and is not useful without an account.

If your app is free, but a subscription to your content is not, the most common practice is to not allow users to pay the subscription fee through your app at all. If users can't pay through your app, then Apple doesn't get a dime.
