Why would you expect anyone in that position to expose themselves publicly? Although they could give useful feedback, it wouldn't be in their interest to deal with these issues outside of a formal process. Unless of course it's in their job title to handle developer relations. Even then it'd be more setting up coordination and less anything technical.

Granted without knowing what exactly that process could be accessed or what it is, I agree that you need to do something to "start the conversation." However, attacking is unlikely to achieve the results you want. This is especially true considering the imbalance in your relationship with Apple. I've worked a number of years in enterprise software and for large enterprises. You have to learn how to bring attention to issues and escalate them constructively and professionally. You also learn that you don't always get what you want.

Do the blog posts but be aware of the tone. Use the mailing lists. Get others to raise their voice and show that it isn't an isolated incident.

In the meantime, since the issue is out there and details are known, workarounds need to be figured out that can be implemented. Short-term, there should be things that can be done by app developers. Longer-term, a solution probably needs to be put in place in the project that will address the needs of both app developers and Apple. (Apple dropping use of the project may be a possibility but I don't see that as a win for anyone.)

Also realize that an app developer "losing an entire afternoon" is minor in the grand scheme of things. However inconvenient it may be to be that developer, unless it's an absolute show-stopper, any reaction or solution will take time if one is implemented at all.
