Yes, it is about antitrust and monopolies. Many of us want competitive free markets. We need policies to fight the natural monopolies of the recent past, with a recognition that network effects and financial concentration have made monopolies and oligopolies much more dangerous.
Alas, the government has largely been captured by these financial interests. And the consumer is giving up freedom of choice for convenience, and not paying attention to this seemingly abstract problem. Thus the outlook for fighting these interests is gloomy.
