But make no mistake that McDonalds is a business that is, if not as harmful as Philip Morris, gradable on the same scale. For the most part it's a company whose core business model is "leverage unfathomably vast marketing resources to coerce large numbers of people into making the least healthful dietary choice available to them at any given moment".
Let nobody suggest that I am a foe of the french fry or the well-constructed burger, but there's a difference between an occasional indulgence --- or even between the ambient availability of that indulgence and any group of people's poor decision making [oh, hi, me!] --- and the business model that depends utterly on persuading the most persuadable people to harm themselves, for no other reason that they were persuadable.
And so it's in that light that I think cynicism towards new "honest" attempts at persuading people is fair game.
Also their burgers are pretty gross.
