I’m definitely not saying we give up, but this absolutely does impact every developer, not just OS developers. Go read the bill, but here are the relevant parts:
(c) “Application” means a software application that may be run or directed by a user on a computer, a mobile device, or any other general purpose computing device that can access a covered application store or download an application.
(e) (1) “Covered application store” means a publicly available internet website, software application, online service, or platform that distributes and facilitates the download of applications from third-party developers to users of a computer, a mobile device, or any other general purpose computing that can access a covered application store or can download an application.
(f) “Developer” means a person that owns, maintains, or controls an application.
(b) (1) A developer shall request a signal with respect to a particular user from an operating system provider or a covered application store when the application is downloaded and launched.
Based on a very narrow reading of the “covered application store” definition, a personal website that only has applications developed by that person might be able to get around the age bracket request, but the application itself is still covered. As things like itch.io, crates.io, flathub, PyPI, and every package repo.
But they can fine every single developer of every single application. Sure, a lot of people won’t be in the jurisdiction of the state of California, but there are a hell of a lot of developers who are.
