This is one of the most ignorant, poorly written articles I've ever seen on Hacker News. it doesn't belong here.
Edit: I'd also say that a certain section of startups are in on the game too - how many startups can you recall where their sole raison d'être and exit strategy was to be acquired by Google, Facebook or Apple? The dropboxes and facebooks of the startup world are much more rare.
Back a dozen years ago (omg, has it really been that long now?), you'd IPO and use all that new money to hire people to take care of the actual business management for you. A founder could get back to hacking on new, fun stuff, or let his board bribe him to step down :-)
