Capitalist countries still centralize their control, surveillance, and communication into few hands with little diversity. The market forces you describe only apply to the early days of capitalism. Most capitalist societies are long past that, at a stage where the strong early players have re-written the rules and formed quasi-state monopolies.

Just look at how many communications companies the US has. And the government had to step in and break that up because there used to be just one. Even now they are quietly conglomerating back together, and there are no significantly different options available. It's still very vulnerable to an attack or flaw due to lack of diversity.
