Now, that would mean NSO has no logs on the phone numbers used to install Pegasus. I don't see how they would allow that
If that were true, any country (Saudi Arabia, UAE, for example) Who got a green light from the Israeli weapons export to purchase Pegasus, can now spy on the Israeli government, army, everyone at NSO, the Mossad, and 8200. And the Israeli's would never know? No way
NSO is playing dumb by saying "we can't know if you were hacked without your physical phone in our hands"
