At the risk of derailing the thread, that would be the lesson I wish people would take away from that example.
Criticizing fast food like that is dumb signalling IMO; McDonald's!hamburger != homemade!hamburger. It's an entirely different product sharing the same name and some of the ingredients. It tastes different, and has a different form factor. People like this, even if many don't want to admit it to others (or themselves). When I go for a McD's hamburger instead of a foodtruck one, or when I say I prefer chain restaurant pizza over a home made one, it's because I want a different product. Treating the two as the same category is like treating tea and coffee as the same thing.
