IMHO it's our duty as technical users to advocate for a more private, open and de-centralized web for everyone.... We should especially be doing it on behalf of the users who don't understand the long term implications of Google's (anti-) features.
'Just switch to another browser if you don't like it' is not a compelling argument.
Every tool in the toolbox to make the web better.
In that context, it's a bit cynical to belittle the problem as you are doing there when this has been a very real issue for several years. As by now Google, Facebook, and Amazon control the vast majority of web traffic and have been doing so for years already [0].
This isn't some hypothetical scenario, it's something that's already very real.

The whole idea of AMP pages is sketchy by default, as it's Google taking content from websites run by news media outlets and hosting it on their own servers so they have even more control over user-tracking.
In the long term, this has the potential to further centralize the Internet, something the Internet was never meant to be.
It's not that difficult to imagine a future where news media won't even host their own stuff anymore but instead outsource it all to Google.
Very comparable to how Facebook has become the de-facto place for small businesses, with little to no IT knowledge, to have their own little web-presence.
Which has certain advantages, but it's dangerous to belittle the very real disadvantages that kind of centralization of content will have in the long term.
