The "give you wings" wasn't literal, which is what the GP was complaining about. FTA linked in the article: "Red Bull does not, it turns out, give you wings — even in the figurative sense. Red Bull says in its marketing that the drink can improve concentration and reaction speeds, but the plaintiff in the case said these claims were false and lacked scientific support.
