The fundamental change is that now the content comes from Google's servers. Google is hosting the Internet.

Of course Google can't host illegal content on their service, right? And won't host content that goes against a future AMP user agreement...

From there they can tighten the screws against competitors, or future attempts at privacy, or basically anything they get away with.

Do you also think that CDNs are bad, since you end up accessing content from the first parties?

[UweSchmidt]

With CDNs I can decide which to use for my site, if any. If AMP gets established as the "new HTML", the new way Internet content is provided, then it's under Google's control.

Your concerns don't give them any more power than controlling the search results already gives them. They are free to deindex anything.
