Keeping secrets is only one option. Another is the cost to duplicate. Your myopic understanding of manufacturing processes likely cannot be alleviated in the comments section here, but just consider that the cost to build certain chip fab plants is up in the billions and takes years to build. Once the first entity builds that, it is guaranteed a profit for at least the number of years it takes to build a duplicate manufacturing process. This is true under any definition of a real free market, making your assertion false.

>In other words, fuck man, capitalists hate markets.

Nope, you mean incumbents hate markets. I think you need to revisit the definition of a capitalist. A real capitalist dreams of when they can come in with a better price/service/product and unseat the incumbents.
