Oh yes I see it now. You posted it right after my response. And I do agree with what you say there. I however do believe that the destinction between a true monopoly and a dominant market position such as steam has is essentially irrelevant in this context. In a market economy you would expect very few (or even no ? ) true monopolies except those run by the state. And not being a true monopoly doesn’t stop dominant firms from being able exploit monopolistic powers.

However my point is that steam doesn’t exploit it’s market position while it could definitely choose to. On that we seem to agree I think
