My understanding with such apparent truths is that even if its noticeable to an individual its a question of his personal opinion vs prevailing wisdom. so in his mind he runs a quick calculus on the cost of changing other peoples prevailing opinion and possibly alienating them of just giving in and buying the damn thing. Now when it is said out loud by somebody with enough critical weight then that calculation shifts dramatically & it may be worthwhile speaking up again. once that opinion is out there you can move that conclusion out into your model of the world instead of keeping it in your personal model so essentially you are unburdened from having to keep that mental context alive within you and you can more easily move on to the next step from there. IMHO this is how diamonds have proliferated for so long despite having minimal intrinsic value.
