You're right, it's an ad at the end of the day.
But there are much worse (debatable) products that spend money on really shitty ad campaigns. So this isn't really bad.
I personally respect Red Bull for having found a niche (crazy adventure sports of all sorts) and making possible whole careers in these amazing sports.
At the end of the day, not a lot of people believe you NEED Red Bull to make this jump, but thousands of kids around the world are being inspired right this minute.
