“Developers are permitted to have a single plain link on one screen of an app.”
The Supreme Court let the anti-steering order stand, and Apple answered with a 27% commission on purchases made through the outside link. That is three points off the standard 30%, before the developer pays its own card processor. Apple still approves the link, limits it to one screen and shows a warning when users tap it. The court told Apple to open the exit. Apple put a turnstile on it.
