Yes, but even in those cases the agreements are much more specific.

And do the terms of service they agreed to allow their provider to 
reclaim the address space from them immediately and give it to someone 
else? If so, fine. But that's not what legacy holders agreed to when 
they received their allocations.

They could very well be "using" their resources for exactly the sorts of 
things that were permitted when they received their space... like using 
them internally for a network that is not directly connected to the 
Internet at this time.

If their POCs hadn't been changed without them knowing that. Or lost due 
to a DNS lapse that was exploited by the hijacker. Etc, etc.
