Copyright reasons.
But nevertheless those 261 zones are watched to be synchronous to the
ICANN root. And there is another check that sees when suddenly a new
zone appears like it did for '.eu' some month ago.
Both Public-Root and ORSN had it the very same day.
I have seen when ORNS and ICANN were out of sync ORSN hat the information
from the zone file for 'at', '.de' and '.gr' while ICANN had stale
information for a very long time.
Same went for '.ke' and the Public-Root for a month or two.
