I feel like I wasted my time reading that. It amounts to a big "Boo hoo!", makes tons of unsubstantiated and emotional assertions ("I can guarantee you that no one ever really gave any consideration to our arguments", the "the process is bullshit"), and the real solution is to just resubmit the app with a non-spammy description. How hard is that?

The appeal says "We don't profit from it, and thus have no incentive to spam." So change the description!
