Depends on what you mean by "an open web". If you consider "an open web" to be a publicly accessible network of documents and applications, it's practically absurd to suggest that Google - a company that makes almost all of its money from services that need to crawl everything it can find on the public internet - might want to hurt this. The more websites and applications that join the open web ecosystem and open themselves to public crawling and searching, the better it is for Google. Walled gardens like Apple News and Facebook Instant actually run counter to this open web. They can't be publicly indexed or crawled or searched, yet they have the valuable advantage of being really fast. I see AMP as an aggressive optimization designed to bring web performance up to par with native platforms like Apple News and Facebook Instant. When a publisher chooses AMP instead of exclusively using those closed platforms, it's a win for the open web when their content uses web standards (AMP is merely a strict subset of web standards) accessible by anyone, not just Apple or Facebook users. I think nowadays "the open web ecosystem" has come to mean something different in discussions like this, closer in meaning to "the distributed web" or "a less corporate web". Google obviously doesn't care for that.
