If you're selling people hands-on classes in underwater basket-weaving, it's probably not a good idea to make all your classes free so you can chase VC money. On the flip side, if you've created a social network that's on track to become the biggest website ever, it's clearly unwise to sacrifice that massive potential by cashing out early. One-size-fits-all arguments ("All companies should go for the gold!") don't make any sense, and are probably issued by people who have a direct incentive for their arguments to become reality.
