California passes a bill which will require developers of any operating system to implement a kernel API which will require that users of the operating system verify their identity when using the system.
This is supposedly to protect children from the dangers of downloading apps from the app store provided by their computer or mobile device.

The bill would define “covered manufacturer” to mean a person who is a manufacturer of a device, an operating system for a device, or a covered application store. The bill would require a developer to request a signal with respect to a particular user from a covered manufacturer an operating system provider or a covered application store when that user requests to download an application. the application is downloaded and launched.
