True, but is that relevant? All companies, big and small, depend on all manner of services, materials, infrastructure, etc that are provided by other entities.

Even if that's true, what does it matter and what are you implying? No innovation because the big good corps paved the way before that?

Imagine what would happen if Rome made those big and long roads all across Europe and then nobody used them out of respect of all the labor that went into them. :D
