Who is 'they', and under what authority? If you're thinking about RIPE or ARIN, legacy block allocations predate those organisations even existing. They have no rights over that space.
At the same time, IANA has delegated 'future' (read: sometime in the past, but not until after those legacy allocations) responsibility to the RIRs (ARIN, RIPE, APNIC, LACNIC, AFRINIC).
Finally, how do you determine whether or not space is used? Ping? BGP announcements to the Internet of the space? Neither of those concludes that the space isn't used, and RIR policies permit for registration of globally unique addresses without any obligation to announce to the Internet.
