On the eight episode of Ore no Imouto ga Konnani Kawaii Wake ga Nai (Trans. My Sister Can't be this Cute), also known as Oreimo, Ito Makoto (School Days, 11eyes) tweets that he was not happy with the episode.
To those who are wondering, the said episode talks about a dispute between an anime producer, who wants to alter the story of the original novel to make the anime more catchy and profitable, and the original author, who opposes to the alternation. Ito said, it is an exaggeration between the disputes of the two sides and it should never be made into a joke.
Here's his tweet regarding the episode:
The relationship between anime producers and original authors is a delicate issue in the first place. Why did they make it more complicated? It's our job to create a cooperative environment with the original authors. It's never occurred in my anime projects that the both sides take a hostile attitude to each other.
The director of the series, Masunari Koji was also depressed to watch the episode and said "I realized how anime producers are looked by the original authors."
