Because, let's be honest, Apple doesn't want to set a precedent that they'll do that without first trying to resolve issues with developers. It's a super bad look for them to just immediately terminate any agreement they have issue with and would just push developers away from attempting development on the platform. Apple has all the leverage in this situation and a ton of good will built up among developers. They want to give Epic a chance to admit wrongdoing and resolve the issue.
