Apple has it's 'rigorous' app approval process, why is this not found in there? I've gotten rejected for all kinds of stuff. But I guess they are not doing any quality checks on the apps during this approval process? Here I've justified the $100 yearly developer fees in that they have this rigorous checks, but apparently they're not really checking the apps? This is apple failing us, nothing else.
