As soon as they are in violation of the license, they no longer have permission to redistribute the code, because the license is the only thing that allows that and it only allows that if they are in compliance with the license. So there is cause for a lawsuit immediately, not after any other action.

They could, but clearly according to the article, they are not doing that. They are first revoking the license and notifying the affected party. I assume the lawsuit will be filed as soon as they have evidence that the notification is served yet the violation is continuing.
