Here's the thing about the scenario in this post: the founders and investors that are swinging for the fences and taking big risks probably have their nest eggs in place. But what about their employees? A modest exit could mean security for them. That exit may not cement the founder's "legacy", but it might give a few, a dozen, or even a big group of people a stable financial footing for the first time in their lives. What's more important? What has the most utility? I'm honestly not sure.
Having been an employee in that scenario and now a founder, I can see both sides. Personally, I'm glad to see more investors making sure that early employees get an opportunity to get a bit liquid if their founder bosses decide to shirk acquisition offers and spin the wheel of IPO fortune.
