Nobody at all is asking them to pay for it.  But do you seriously
expect their routing tables to become full to bursting because, for
example, they checked the ARIN route registry, RADB etc instead of
blindly using minimum prefix size defaults?

Or are swamp space legacy IP ranges with minimum prefix size of /24
that easy to get in this day and age?
