> Bloomberg's app (Bloomberg Professional) is unusable without an account, which is 100% against iOS guidelines, but who cares? Other big players, such as Amazon, simply negotiate the Apple tax – instead of paying the 30%.

Both of the companies mentioned don't make money from the use of their app -- at least not directly.

Sure, you can do all of your purchasing w/ Amazon through their app, but the website remains available if that is more to your liking. For free apps like Google Calendar, this is also the model.

Bloomberg's app is a front-end to the Bloomberg Professional Service (colloquially, "The Terminal") and to read more than a few articles or access any of the data sources, you need to sign up.

Tl;dr It's not cheap

Free trials can be converted on iOS, but -- and correct me if I'm wrong -- require going to a web browser instead of it all happening inside of IAP, although, that could come along at some point...

(Based on no inside information, that might be the case this fall, check back in a few hours to see if it actually comes to pass)
