First, we DON'T know the whole story... only what we read here and that was a lot of speculation. Second... even if Apple reversed their decision, that's a good thing.
Seriously.
Some random employee may have thought the rules said something and rejected the App. Apple then clarified the rules and the App was resubmitted.
Anything could have happened.
The stupid part of all of this are the developers who think they need to go on some anti Apple PR campaign before the issue can be resolved. Makes them look like idiots to people who follow all of it but the negative PR will stick to Apple even if its not appropriate.
