@Libra You know, its funny. I’ve been meaning to create an opinion piece regarding this topic. The question is not new, and has been asked a bunch of times. Heck, I had the idea for the opinion piece when I first saw this on the subreddit.
So here’s the first thing that came to my mind - a lot of fluffy stories have already depicted fluffies as being sold. So in a way, they already made it to sales floor in some canons.
That is assuming that fluffies in all or most canons aren’t completed. And that isn’t always the case. Some stories have it that Hasbio released fluffies as intentionally flawed. Assuming you were working with a canon stills et or close to MLP, or near post-Cleveland, then fluffies would be incomplete. But over time, the fiction became less about fluffies being incomplete, and more flawed, either due to intentional corporate oversight, or it being just a part of their nature.
While working on my Avocado series, I have been chatting @Carpdime about an idea that seems quite evident is that, at least in the “Avocadoverse”, that fluffies are based off a “My Little Fluffy” cartoon, which can be imagined to be a “Muppet Babies” version of MLP, the way fluffies were a cutesy baby-ish in-joke create by early bronies on 4chan. The idea behind this approach is that fluffies are complete the way they were intended, but poor management and the like resulted in them becoming a nuisance (at least first).
I really think that, for fluffies to be popular, they have to be based off something popular in-universe that spawned them. Its something I feel the anti-brony abusers never understood about MLP, let alone fluffies - for fluffies to be popular, they have to understand why people would want the product in the first place, and why MLP was the cultural phenomena it was at one time.
First response - there’s more than one world. Different artists/writers have different interpretations and headcanons. Some ideas are recurring, but you can’t say “the one they got instead”, because we all don’t operate within the same world. The Avocadoverse does not take place in one with The Fall of Cleveland, and I imagine the same might apply to Plum, and so on.
Second response, I’ve been writing Avocado in that vein. Where fluffies are treated as a sort of sentinet pet with rights, but their population was the result of poor management due to being an “animal marketed as a toy”.
I recommend reading an opinion piece I also did regarding whether fluffies are an animal or biotoy. And I need to get round to writing the opinion piece regarding my opinion that fluffies are perfect “they way they are”.
I feel there is a distinction between a fluffy that is sold as a product by a coproration, and a fluffy that was born feral and only knew the free life. Or better yet, a fluffy that has seen the horrors of living under humans, and preferring living the free life. Its part of the reason why I feel that the Blade Runner approach should be seen with fluffies - how much rights should fluffies have, based on their restrictions? Of course, its very much open to debate, and there are no easy answers.
