I'm going to respectfully disagree.

Whether a product is being funded by Google or a VC, I'd argue they have a similar desire to make money, or else cut funding.

If a product looks like a failure, the startup isn't going to keep it going or try harder -- the VC's will want to cut their losses.

I honestly don't think there's much of a difference at all. It's the same types of executive tech people making the decisions at the end of the day no matter if it's at a VC or a Megacorp.
