I don't see a definition for "operating system" in this legislation (California).

"Operating system provider" is defined, but that's kinda useless unless "operating system" is defined first.

It seems there's also a definition error:

> 1798.500. For the purposes of this title:

> (i) “User” means a child that is the primary user of the device.

Child is defined:

> (d) “Child” means a natural person who is under 18 years of age.

But that means this is impossible:

> (b) (4) Whether the user is at least 18 years of age.
