If you read Tim's tweet, it says in the policy "Ability to ENABLE Apple services [like] Sign in with Apple". This makes sense as Epic no longer has the ability to enable SIWA on new apps.
Says nothing about termination of SIWA on current apps as SIWA will continue to work on existing Apps.

I think Tim wasn't being too honest here.
