Just another gimmick bullshit to show when opposing right the repair. Few weeks ago Apple started blocking battery replacements in iPhones, even original ones swapped from another original iphone.
As an end user you will not have to care. It just (rightfully) takes a chunk off the resell value.
Nothing prevents you from using it as usual. It's essentially just Apple writing "battery has been replaced by not-us, please don't blame us if this doesn't perform as expected or like, explode" in more obscure wording in their system settings.
It doesn't work with the original battery because... the company selling that IC to Apple didn't design PKI into them? The critique video literally proves this. This authentication scheme is designed by TI.
