Maybe they'll get bought via a talent acquisition but as soon as their golden handcuffs are off, they are out doing their own thing again. The reason they allow themselves to get bought via talent acquisition is to be able to easily raise money in the future.
I think Sean Parker is reacting to these types of people. I think the misconception is that the increased funding sources is what is driving these people. I would suggest that they were always there, but 5 years ago they were just living poor and working their ass off to build a startup (usually unsuccessfully).
I do believe I'm part of this group. There's no amount of money that would compel me to take a corporate job. Sometimes money isn't what matters.
