Would love to see arXiv set up as a consortium of international academic libraries instead. Scientific publishing is where it is today because universities and scientific societies sold off or gave their journals to private enterprises. Letting Google in is a move in the wrong direction imo.

Some sort of federated preprint protocol where anyone could stand up a node and clone the existing data would be ideal. The current centralized operator then becomes "just" a curator (and competing curators are easy to set up).
