The author here has a point.
The collective internet is kind of like the little kid in AI: Artificial Intelligence. When it loves something, that love is the most passionate, powerful and awe-inspiring thing. And if you even slightly interfere with that love in any way, it will destroy you with a cold, mechanical fury.
Particularly since the author was referencing what happened when they made a live-action Avatar: The Last Airbender — No! Sit back down! It’s OK! It’s OK! The franchise is dead! It can’t hurt anybody anymore! You can even click the link; it goes to a Blu-Ray of the real show. The animated one.
Anyway. See what the author meant?
