Privacy routers, phones, and computers?

At the most basic level, this “privacy” stuff just means changing the operating system!  It’s the same hardware and many of the same programs/apps are used.  The only real difference is an open source operating system that isn’t spying on you.

So with a computer, we’re ditching Windows/Apple and using Linux.

With a phone, we’re ditching the “stock version” of Android (which is the version with Google’s telemetry), and using GrapheneOS (or other choices such as Calyx, Lineage, etc)

With a router, we’re ditching the ISP or manufacturers’ version, and putting on OPNSense, (or pfSense, DD-WRT, or Open-WRT)

That’s it.   It’s not that complicated.  You can use the same cell service.  The same home internet provider.  For phones, all the same Android apps.  And for PC, most of the same software.  It’s just that the OS has no telemetry.
