I'm going to have to agree with you here.
I was hoping that the move to Xcode 7 allowing anyone to build and install apps on their device would result in a small but unique open source community for iOS devices. Applications that would not be allowed in the app store because of their license (GPL) or because they do things in a non-Apple approved way could flourish here, and provide burgeoning developers with code to look at and learn from.
Instead, we see the first app released in this manner using a binary blob, totally against the spirit of open source and hacking on your own stuff. I really don't want this to become the norm for outside-the-app-store apps.
And patents are no excuse. Releasing source doesn't get around them.
