I've stopped reading stories like these through a lens of globalism or protectionism, but instead from the perspective of concentration of market power and competition. It seems to me more and more that the mere existence of a Goliath in a marketplace causes far fewer David's to even attempt competition, whereas their breakup or de-integration can cause new markets to flourish (and eventually new Goliaths to arise). The part of the story that seems to be missing above that you would normally see in the USA is that the upstarts in India here were not purchased / tookover / or otherwise integrated by the larger entity. I wonder why this didn't happen? Is there something about India's corporate law or antitrust?
