> From a penetration testing perspective, this may cause practical problems I was super confused what they were talking about, until I remembered that "penetration testing" really just means "penetration", not "testing", it's just a euphemism for "attacking". I think?
I don't even attempt to circumvent SSL pinning. IMO it's easier and safer to use Cydia substrate to decorate the networking classes to print args and return values to the console. I've reversed a few APIs in this way, including a bank's.
Note that the associated whitepaper discusses using Cydia -- specifically cycript -- to do the same thing.

Yea, I think a better term would be application security assessment where one tests the application for security flaws. Penetration testing stems originally from network security where one actually tries to penetrate a network. It's not a great term for software, I agree.
I think the intent here is to decrypt and then reverse engineer the network traffic, so they can then check for vulnerabilities server-side. So they aren't auditing the application, they're just trying to find a way in.
This is part of auditing an application. Finding a way in is only one step of the process.

Yes, often times that can be sufficient. If you just want to study the protocol or build a custom client. Often times one would like to modify messages of the protocol in order to find flaws in either the server or the client and the ability to man-in-the-middle the protocol makes that easier, in my opinion. For completeness, the whitepaper is here: http://matasano.com/research/bypassing_openssl_pinning.pdf
