I'm a super hater of "referencing", of course I have a a lot of influences but still I've seen some much "referencing" it drives me crazy. But this take from one of my favorite blogs Conscientious is a good point,
"Interestingly enough, what gets people so riled up in photography is taken for granted and widely accepted in many other art forms. For example, in music certain artists are just accepted as influences for generations of later artists - without the endless "ripping off" or "just copying" "discussions" that we see in photography. There are occasional discussions about someone ripping off another artist, but these are fairly rare, and usually, they are usually also very obvious (and, often, it's all about money)."
