I have let it get to me. I haven't played Fez because the very idea of it reminds me of Phil Fish, and I just thoroughly and perhaps irrationally dislike that dude. Other times I just enjoy the art separate from the artist. I don't have a code that I live by or anything.
Why not think about it from the perspective that the developer hadn't considered it might offend someone and after having the discussion with whoever it was, agreed with their perspective and wanted to change it? Why is everyone assuming the developer doesn't have a choice in this or is somehow terrified of repercussions if they didn't make the changes?
If the developer wanted to make the change shouldn't this be trumpeted as a success for community engagement?
I'm going to assume the developers knew an image of a child on fire was intrinsically offensive. That's really the point of the "gag", whether one thinks it's funny or not.
