What makes you think so?
If a market entrant wants to get an edge on existing incumbents, they will look for opportunities to operate at lower costs.
If a non-free component can be rewritten and redistributed at a lower cost, then eventually it will be, either to improve margins or by a market entrant.
This is why I expect that the article's proposition that the marketplace should expect to pay for a component will crumble over time.
is .NET paid somehow?
could it be cheaper? maybe in terms of hardware, but overall?
(you also make a very observant hint: total cost of ownership includes hardware-level resource provisioning)
