Well obviously we want to know more about the procedure and why apps get rejected. We want to know what Apple's "moral" objections are and what values they're trying to impose. Its more a fear of some agenda (beyond no apps that don't work or do harm) that we may not agree with then stats.
It also doesn't hurt to know what your chances are to have trouble.
Misleading statistic - developers are probably just getting better at self-censorship. They don't bother submitting non "politically correct" apps anymore.
