I agree, as it seems like it allows people to basically curate their google results so that only positive things appear about them.
I agree there should be circumstances where content should be removed from indexes but if the content publisher is not required to remove it, and it is legal content, why should google or other search engine providers have to stop indexing it?
What I believe would be a functional system would be that a court order for the content publisher to take down the content should also require google to quit indexing the content, so cached versions aren't able to be found and in case the publisher doesn't comply. But that having a ruling that google has to act as a gatekeeper to legal and already public content about an individual because they feel it is not relevant any longer does seem like a dangerous precedent.
