I am very much in favor of open access, but there is one service that these publishers could definitely provide that would definitely be a value-add: replication. I can imagine a prestigious journal or publisher using the money they've collected to sponsor studies that replicate results. I need to think more on how this model could work such that piracy doesn't circumvent it, but I think there is definitely a need for more replication studies and prestigious publishers have an incentive to ensure that their studies are replicable.
