Devices exist on a repairability spectrum, from the industrial appliance which is delivered with full electric schematics and every part stamped with a replacement order number, to the black-box NUSPI ["no user serviceable parts inside"]. The enmity is not really about batteries, but having that one question stand in as a measurement to ensure the device meets a minimal standard for allowing third-party repair.
