To me it's about the control more than it's about the money. If preferred shares got half the voting rights as common then the difference between a 10% seed and a 15% seed isn't as bad, but after accelerator / angel takes 7%, seed takes 15% and possible bridge + series A takes 30% you're down to raising a series B and admitting that you're no longer in control of the company.
