Agreed. However, effectively saying "I don't care about the meat, just drown it in sauce" is a different matter. The article is intended for those who do care about grilling good and flavorful steaks.
With pork ribs I actually agree: I drown them in BBQ sauce and pretty much only care that they are tender.
With steak and cow cuts... hey, I'm Argentinian, we care about our grilled meat [1], the thought of just not bothering about how much it's cooked personally offends me!
[1] though not most restaurants. Given the importance beef cuts have in our diet, it's surprising most restaurants just don't care. They will either serve you meat so bloody the cow might as well still be alive, or something that is hard, chewy and not tender at all ("the sole of a shoe"). Honorable exceptions exist and tourists seem happy even in the worst restaurants, so what do I know?
