Thank you interop for setting the example.
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.

John, could you provide more details at this stage on how much address space
was returned to ARIN?

ARIN today recognizes Interop, an organization with a long-standing presence in
the Internet industry, for returning its unneeded Internet Protocol version 4
(IPv4) address space.
Interop was originally allocated a /8 before ARIN's existence and the
availability of smaller-sized address blocks. The organization recently
realized it was only using a small portion of its address block and that
returning the remainder to ARIN would be for the greater good of the Internet
community.
ARIN will accept the returned space and not reissue it for a short period, per
existing operational procedure. After the hold period, ARIN will follow global
policy at that time and return it to the global free pool or distribute the
space to those organizations in the ARIN region with documented need, as
appropriate.
With less than 5% of the IPv4 address space left in the global free pool, ARIN
warns that Interop's return will not significantly extend the life of IPv4.
ARIN continues to emphasize the need for all Internet stakeholders to adopt the
next generation of Internet Protocol, IPv6.
