In some ways, even cellular connectivity itself is problematic or any baseband system that requires some form of out-of-band processing to function (even if it doesn't "call home").
Most people won't know (or care) about any of this anyway, and the disruption trade for some invisible gains that are supposed to come out of unplugging like this isn't likely to attract any reasonable mass of users to do it. It would probably be mostly destructive anyway considering the information flow of civilisation depends on so much of this integration now.
Technically we could do without all of this, but practically it would be luddite's errand to try and do any this.
I wonder what we could do instead, but considering the min-maxing for profit sets the stage today, I doubt someone can come up with an alternative that yields the same (perceived) benefit from using Google's or Apple's technologies.
Considering most new people from the past few years are primarily mobile users and a lot of those never even had access to (or a need for) a desktop-like type computing, there is very little mindshare about what else might be possible in the digital realm.
