If "truth" is something that keeps people from entering the pleasure machine, that is because they value the pleasure of truth more than their estimate of the pleasure derivable by the machine

So, is the 'pleasure of truth' somehow more meaningful than the pleasure provided by the machine? Objectively, the pleasure from the machine is greater than that from the truth, which suggests that there's something more than just pleasure. Doesn't this contradict the views of meta-ethical hedonism?
