Okay, so I am founder of the company, I get VC funding. But I’m not “rich” by any means since I only have the play play wealth based on illiquid “equity”. I may not even have control over the company any more after much dilution.

I get an offer from Google where I am now making real money and have liquid RSUs coming. You think other employees should have the right to sue me because I left the company for a better offer?

The investors aren’t getting anything, in this case Google didn’t acquire the company, they hired the employees. Why would the investors be sued because employees left?
