Epic claims Apple just reversed course on “Sign in with Apple”

From the Epic “Sign in with Apple” FAQ:

Apple previously stated they would terminate “Sign In with Apple” support for Epic Games accounts after September 11, 2020, but today provided an indefinite extension.

And this Fortnite Tweet:

Did Apple reverse course here? Or is there more to this story? One likely result is Fortnite users switching from “Sign in with Apple” and moving to an email account-based login. Which gives Epic more user data.
