Actually, even this statement is slightly FUDish, depending on one's
perspective.

What I suspect you mean when you say (elsewhere) that ULA+NPT costs
nothing is that it costs /you/ (or "the network operator") nothing.
But there is a cost, and you've just moved it elsewhere.

Such is your prerogative, of course, but let's be clear: it has non-zero impact.
