Also - if I build a business around a 10 person startup, and they run into trouble or get acquired - there's at least some chance I could negotiate to buy/lease/rent the piece of IP and platform I'm relying on, or to reasonable expect to replicate the important bits of APIs I'm using by starting my own 10 person team. I cannot ever expect to "negotiate with Google".
