This news is like a dagger in the heart for small ecommerce stores like me. Amazon is hard enough to fight but what's going to happen when you have these to giants in the same war competing against all of us small shops.
Maybe I'm missing it but Google's latest involvement here seems to be aimed at getting very large brick and mortar stores with lots of physical locations to ship stuff to customers from the physical location closest to them. I don't think this poses any danger to any of us who aren't competing with very large brick and mortar stores with lots of physical locations. I think it's way overblown to say this affects all of us small shops.
