It's not for a cool 20 minute video. It's for the collective viewing time of some 2.2 billion minutes of entertainment. There is no reason to use bootstrap-budget on the supply when the demand is this high.
Viewing stats for some videos/events can be hard to get your head around. That's about 50 lifetimes by my calculation.
Also, a social media website is probably not the right place to point out that other people are wasting their time...
