There's something ironic about the criticism of Facebook internally as a popularity contest, then making $500,000/year from advertising on your popular YouTube channel.
Or to put it another way, if you work hard get a good degree, get a job at a top tech company and then find out your success boils down to the same skills you need as a youtuber, you may as well just quit and go be a youtuber - especially since being a youtuber could pay better and you don't have to pretend to add features to facebook.
I heard it as a criticism of deciding work decisions based on popularity, with product choices, technical implementations, etc... based on facebook likes, not real deciding factors. Which is very different from growing a YouTube audience.
