Not only that, but the "entitlement" (Apple lingo for code-signature flag that grants capabilities) needed to publish a browser effectively requires to be an established company, ensuring hobbyists can't really get there with an open-source project even though the sources of Firefox are available and could technically be ported.
It goes well beyond requiring an established company. It's so onerous that no company has yet successfully navigated all the gates required - even Google. Apple is maliciously complying with the EU's Digital Rights Act, and many years later, the EU has not concluded its investigations. I am incredibly disappointed.
