If it wasn't deliberate they would let you install Chrome instead of forcing you to use Safari with a chrome skin. And why do they have Safari with a chrome skin? Because then most gullible users thinks they can actually use chrome and that chrome and safari are mostly the same, when they are actually really different and they therefore don't understand what they are missing. Even here on HN where people should know better you sometimes see users say "if you don't like safari you can just install chrome!".
But I guess that's the whole point of the discussion :)
