I think there's a certain type that you're talking about that does tend towards energy drinks like that, but it's not true in the other direction, as that type is a minority of energy drink drinkers. Just a particularly noticeable one.

I've not been a fan of them myself since I was a teenager years ago, but I've worked with quite a few people in all sorts of roles, whose drink of choice was whatever their favourite energy drink was, either having one occasionally or between one and a few a day, while being completely relaxed, mature, and just nothing to do with any sort of stereotypes you might think of in connection with energy drinks.

Sure, I guess I've just worked at enough startups that advertise "keeping the fridge full of Red Bull" as some kind of perk, when in reality it kind of ends up being a code for "you'd better enjoy working long, long hours".
