The old "interview screenplay"[1] post on the Matasano blog
had a particularly compelling image of Why ECB Sucks. Sadly, it doesn't seem to have survived the 3 years of blog herd migrations.
the argument you're replying to doesn't require that the explanation be correct, does it?
what they seem to be saying is: feeding someone a little extra information that is entertaining somehow helps make the recommendation to use a 3rd party library more convincing.
and i think there's something to that argument, even though i've presented it poorly above. people don't like to be simply told to do something. they like to be indulged a little.
i realise that goes somewhat against your personal style, but it's not obviously wrong...
