>more open
You can have a fully open system with an ARM SBC if you route the GPU tasks through the CPU. Can't get more open than that, although like I mentioned to OP, we might soon be able to use the whole board when/if we get free drivers.
>He truly believes they are great
When did I say that? Allwinner and Beaglebone are the closest to being complete sets of integrated free design hardware which comes together. Am I wrong? No, I'm not.
Look at this: https://hackaday.com/2017/09/23/the-tiny-25-pocketbone/
That black square in the middle of the board is a Beaglebone Black, reorganized and compressed into a tiny package. It's the same size as a Core2Duo CPU and is a full computer on its own (if not a very powerful one). You could do a minimal install of Gentoo with an X display server, Musl, keyboard software from postmarketOS (for a mobile phone setup), and Dillo, add a 5.0 inch touchscreen, solder on a wifi card, and shitpost from it. Free the Mali GPU on that, and it's a fully libre machine.
You can make your own machine with a Core2Duo CPU and other free components, but that's not relevant here. Fuck off, LARPer.

They can triangulate your position by looking at which cell towers you're connected to. That's not even mentioning IMSI catchers and hardware exploits (proprietary basebands connected to everything, firmware, etc).
