Earlier quoted context omitted.
My guess is Apple is bored of truly innovating and now has to resort to nickle-diming customers to hit quarterly numbers. Tim Cook put on his "Make Changing Batteries Expensive Again" hat.
Don't go buy a BMW anytime soon. Have to recode the battery, and it's been that way for years.
If Apple doesn't want to show the estimated health state for aftermarket batteries, that's fine, but they should have simply refrained from displaying that field. Displaying scary but meaningless warning messages just comes across as rent-seeking behavior. It will (or at least it should) encourage their customers to contact their representatives to support Right To Repair legislation.
