Apple is not going to waste their resources on niche product categories which barely bring in any money for them.
I don’t think you understood that members post, As they alluded to products like the HomePod Mini Being a potential future Product, Thats hardly a ‘Niche’ category, considering they likely will offer a secondary version of the HomePod at some point. Not to mention, the HomePod is a completely _separate_ category for Apple and they still themselves are figuring out where the demographic is for this specific product and how it will expand.
