No...get off google

My main question would be: does it include protection from Google itself?

Huh, seems more about locking Chrome down but doesn't touch on Webviews.

The simple answer for me is no. Anyone is welcome to correct me if I'm wrong, but it seems to me that Google is moving to enhance security for users who are at a higher risk of targeted attacks, such as journalists, activists, and public figures. They are implementing this under the guise of security.

Additionally, they appear to be seeking to protect the ecosystem against open-source developers and outside developers who choose not to use Chrome, the Play Store, or other Google-based offerings, effectively reinforcing the operating system to maintain control over the Google monopoly.

Google's reference to Apple is an admission of their plans in my opinion although I believe there is more to this which I won't go into.

Once APP is activated, many non-Google applications are blocked from accessing Google services, which can hinder the use of alternative apps that users might prefer. My question is: wouldn't the focus on monitoring and restricting access to accounts lead to concerns about surveillance and the extent to which Google monitors user behavior to enforce these protections?

It sounds like a slippery slope to me.
