The 'other industry' part. AMP clearly expands and entrenches their power in parts of the web they are already in, but it's unclear what other or newer industry it is supposedly helping them dominate.
Indeed. They control the content, and the technology: It could become technically impossible to provide new alternatives for ads, privacy, or any other future use case or interaction.
Browsers, mobile operating systems, ad networks, comparison sites, video hosting sites, image search, map services, etc., etc., etc.
All of Google myriad of properties benefit from being able to limit competitors web page size, limit their technology use, restrict advertising and gating them behind your own servers.
Plus on top, Google doesn't have to do any of that shit themselves and can gleefully put themselves at the top of every search (and are doing with an ever expanding array of search terms).
As well as increasing the cost of developing a site to compete with any of Google's myriad properties, by having to support HTML and Google's proprietary AMP, that they're pretending is an open standard but is completely under their control.

Why shouldn't a company be able to decide what they feature on their search results and how they rank things? If every result was a Google owned site, so what? Nothing is stopping you from using a different search engine.
