I don't see why people are sore at this. It was kinda funny.
I tend to agree. The leaving "narrative film" line made me chuckle (though I refrained from clicking the link to read more).
I think some folks complain because that's their schtick - they enjoy stomping their foot and pointing their finger in condemnation because if the joke ain't theirs then it ain't funny - no exceptions. It's insecurity on their part and it shows.
All in my super-duper-humble opinion.
