The key thing to address is the near zero marginal cost part.
If the philosophy extended beyond a binary blob, we would have a whole parallel economy of free tangible goods, from workers using their expertise on their own time. But this basically doesn't exist because real costs are involved.
This thread started with me citing a counterexample to your wide sweeping attempt to lump self-interested corporations in with humans who tend to be generous under many circumstances. I've made my point, so I'm done here.
What about books or art or movies?
The electronic version of all those is also near zero marginal cost.
