I would interpret the Apache Licenses terms on breaking the license to apply to patents and there it is pretty clear that the party who starts litigation loses their own license. I don't think any open source license writer would intentionally want the situation where a middle-man causes a license to never be valid, and in this case it makes no sense as attribution is meant to be optional information.
