It's a very open and transparent standard that doesn't stop others from adopting or caching it as well. It just so happens that the nature of caching favours big players like Google, but Cloudflare or Bing could offer a cache as well. I fail to see it as some sort of Google ecosystem lock-in. AMP is also compliant with web standards. It just uses Custom Elements which is a fairly new standard.
