This way it will create dozens of tech companies competing with AMP focused on making the web faster - the end result that Google supposedly wants and this way everyone wins!
I would love to see a startup tackling the issue. Creating a score that takes into account load time and other factors. If sites like HN and Reddit would use that score as a ranking factor, then this might get something rolling.
I don't think Google is remotely at that point, and from their competitive perspective they're still winning by letting their open-standards-straw reach all the way across the room and drinking Microsofts/Oracles milkshake.
And for a tech behemoth with Billions of dollars flying around and fingers in all the pies I think Google has one of the, if not the, best track records in standardization. Concretely, when comparing their products at the personal and Enterprise with their competition they're consistently more open...
I think not having a massive clump of RDMB revenue helps them think freely about problems :)
You can't test a page's load speed from Google's servers and then expect it to load for the user in the same way.
Especially because one of the key points behind AMP is the use of CDNs, especially global ones (like Google's, Microsoft's or Akamai), which greatly speed up load times while also reducing traffic for the ISPs.
As far as CDN goes, nobody is stopping you from using it. If you want a site that rival's Google's AMP then you have to use a CDN. The only difference is now it's your choice what you use rather than being dictated to use their non standard tags and technology.
