Sure, it would be a nice gesture if MIT/HP/Ford/Xerox/Halliburton/etc gave 
back the chunks of the /8s they weren't using, but it wouldn't 
significantly affect when the IPv4 well runs dry.  Also, without knowing 
how those organizations have used the space internally, such an 
altruistic gesture could also come at the cost of having to de-aggregate 
a bunch of advertisements in BGP.

The law of diminishing returns comes into play.
