Mostly theoretical headcannon:
In my world, if they had been released normally, the only fluffies sold would be sterilized (either sterile females or wholy un-gendered if they could work that into the design).
All viable breeders would be kept in house by HasBio to control the supply.
This would have given them full control over supply levels, quality and development, including more specialized (premium $$) breeds and the like.
Legally they would have the same ‘biotoy’ status, but without herds of feral pests and low quality ‘shit rats’ there would not be any legal reason to persecute them - in most stories stealing a person’s fluffy and killing it slowly is hardly even a legal concern.
While some level of abuse would exist, the general public would view it much more like animal abuse rather than being accepting of it.
Overall the fluffies would have much better treatment, but would not be a common/cheap. Most stories rely on a large feral population/mills to keep the prices down, but in this setting HasBio would dictate the price.
Bog standard earthies would probably be trivial to get, but other breeds would be more in the price range of a pure bred cat/dog, so would be more high class status than common pets.
I’m also sure that there would be a range of industrial usage for fluffies, so the level of industrial ‘sadbox’ would be much much higher. I’m thinking of a story from a while back where they were processed to produce the same stuff that’s harvested from Horseshoe Crab blood.
And the HasBio breeding stock would probably suffer as much as anything in any standard mill.
Overall the general fluffy population would be better off - but they would still be a product, have no legal rights and have no reproductive ability.
