They have a pre-ARIN allocation, so the rules are different.
I also have a pre-ARIN allocation (only a /24 though.)
ARIN doesn't 'own' the IPs either.
(The fact that MIT refused to recognize ARIN's rights over the IP space was historically why ARIN never gave MIT an IPv6 prefix, or so I hear....)
I've never signed the legacy registration agreement for my IP space, either. I've had it since 1993, before ARIN existed.

What did you do with it ?
With that said, they basically built the Internet so I won't hold it against them.
