Apple sold ~230M iPhones the year the mini was discontinued. 2% is an unquestionable failure.

6/230 seems closer to 3%. And while the number is relatively low, it seems to be a niche where they might lose customers to other platforms. It must have been unprofitable/very expensive to maintain that they killed it.
OTOH, it's Apple, so users would rather buy a bigger iPhone and complain than switching brands (see other comments here), in which case Apple loses nothing.
I don't get that mentality. Millions of units, shares many parts with other models, OK margin. This is no reason to kill a product.
For comparison, that's roughly like Ford killing the Bronco Sport, or VW killing the ID.7.
So much for the long tail I guess. Tough luck if you want anything quirky or unique, society will only manufacture for the mainstream taste.
