You're getting downvoted because it sounds like you're defending the plaintiffs, but you're essentially right. They could have minimized disruption to German users by removing the affected books and committing to remove other books upon request. They instead chose to respond in a very broad way that will draw a lot of attention.

Which, I want to be clear, is a good thing. PG is absolutely in the right here, and this response is well-calculated to raise awareness and put their attackers in the spotlight.
