Of course that is true. I just take a look from my point of view :). Let's hope that after a few years I will change my mind and think big and old sites should be loved more .
But to be honest I would say it is all about measuring. New sites need boost of visitors and should be given a chance - like send there 0.001% of users and measure their behavior - were they long on the site, did they search further etc. That is how it should be done if the site is trustworthy and not age.
