It's quite simple really..none of them has a bootleg node count..If Rybka had showed the real node count and real PV, I doubt that anyone would have went in depth with Rybka in the first place.
Yes, but I don't believe obfuscated Rybka output was to hide its probable similarity to Fruit -- IIRC Rybka beta was searching significantly different number of NPS that contemporary Fruit and the moves it chose was different than Fruit's -- so the reason of obfuscation lays in other place, I think.
But it's true too that at that time noone knew the real numbers so it's quite understandable that suspicions arose.
take it easy :)
