Technology is doing that. Capital, if it was possible, would kill all of those startups and concentrate the market in its hands like it did in late 19th century. And in a way, it is already doing that via investment funds and buyouts. Its just that the Internet is a wild west yet, and it has not been consolidated.

Additionally its the Open Source what is driving this vibrant environment. Before Open Source took hold, it was incumbent major, old school companies who controlled everything. So its not again capitalism - its copyleft ideology that is driving these opportunities.
