ISPs must now show 75-80% utilization of existing address space
prior to allocation of new address space.

To my knowledge they do.  Note that this is a relatively recent policy
shift.  I do know ISPs with class As have been refused new allocations
until they can dmonstrate they have utilized 70-80% of their class A,
however it is easy to hide that you are from an organization with
existing space.

There are many such examples (IBM, PSI, BBN, etc).  However, I do
not believe there have been new allocations to these organizations
in the recent past.

You are basing too much on what companies use for their DNS.  HP has
lots of other address space as well.
