How about the fact that the same guy institutes policies that ban huge swaths of apps (including anything not written in Objective-C)?
Fart apps are essentially the poster child for "crapware" in the App Store. Anytime someone wants to criticize the App Store, they will probably point to apps like the ones he's making. But while Apple constantly expands its list of unacceptable things (the programming language ban is merely the most ridiculous, not the only the thing on the list), fart apps remain the one genre that seems untouchable. It's a messed up state of affairs.
There is literally no evidence to support the latter interpretation.
I doubt the ObjC/C++/C requirement was his call. He may be in charge of enforcing it, but something like that would have come from higher up.
