"AMP keeps users within Google’s domain and diverts traffic away from other websites for the benefit of Google."
No, it keeps users within the link aggregator's domain, whether that is Google, Bing, Baidu, or a link aggregator made by a third party. The publisher is OK with this because it makes loading from all of those link aggregators instant, just like when they publish for Apple News; but in this case, they can publish once and support multiple aggregators.
