I don’t really think Google’s plan is that weird. And it would be amazing for decentralized networks, archiving, and offline web apps. Google can’t just serve nyt.com — they can serve a specific bundle of resources published and signed by nyt.com verified by your browser to be authentic and unmodified.
How does centralizing content on Google from multiple sources improve decentralization? The web is already decentralized. That's why it is a web. AMP is a scourge. It's a bad idea being pushed by bad actors.
I think what Spivak is saying though is right. If we could move from location addressing (dns+ip) to content-addressing , but not via the AMP cache servers, in general, anyone could serve any content on the web. Add in signing of the content addressing, and now you can also verify that content is coming from NYTimes for example.
Also, I'd say that the internet (transports, piping, glue) is decentralized. The web is not. Nothing seems to work with each other and most web properties are fighting against each other, not together. Not at all like the internet is built. The web is basically ~10 big silos right now, that would probably kill their API endpoints if they could.
