I'm also a big Formula 1 fan, they also sponsor some of the best surfers like Kai Lenny and awesome events like King of the Air. I enjoy Red Bull, the marketing.
Not so much the product. The problem I have with them is that they make the money for all this good stuff by selling expensive and extremely unhealthy drinks to youngsters. I'm wondering if they are a net positive for the world, my conscience whispers maybe they are not.
Red Bull may be the only company that I like for their marketing but whose product I'd like to be taxed to oblivion (together with all sugary softdrinks).
