Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Am I Just Paranoid About My New Chromebook?
The OP's computer is one of those Rockchip ARM models. It is much more difficult to get an alternate OS on it compared to Intel models. Maybe this one: https://github.com/SolidHal/PrawnOS

How is the free firmware for the Raspberry progressing?
> I'd hardly argue that the RK3399 SoC is more "open" than any of the broadcom SoCs.
What? The gru-kevin chromebook (RK3399) can be booted without using a single binary blob, absolutely everything (even the arm trusted firmware) built from source. I use mine that way.
I've never seen a laptop with a "broadcom SoC" that could make that claim.

What is the linux community's opinion on chromebooks linux capabilities?
chromebooks fork linux almost as badly as androids. instead of mainline + some patches/modules you get a custom kernel made for the hardware in question, usually with lots of proprietary drivers that make it hard for users to update. this is worse for ARM chromebooks than x86 chromebooks, but often has the same result on both: instead of downloading your favorite distro's ISO and installing it, you need to find something like PrawnOS that supports your specific model. in many cases you can't dualboot either because google's gimped UEFI/uboot/whatever implementation only boots chromeOS, and once you replace it with a custom firmware chromeOS becomes unbootable

Did you get a Chromebook for reasons other than school? If so, why?
You might want to look for an installation guide for your specific model. For example I used this one to install PrawnOS on my Acer C201P

Ubuntu boot on Apple M1 Macs achieved; port to be released later today
the mainstream name is core/libreboot like used here but there's various other custom firmware too

Raspberry Pi receives strategic investment from Arm
> Please correct me if I'm wrong.
My memory told me it was the GPU that needed the blobs. So I asked at DDG
https://duckduckgo.com/?t=ftsa&q=binary+blobs+and+the+Raspbe...
Turned up this: https://wiki.debian.org/RaspberryPi and it says...
> All Raspberry Pi models before the 4 (1A, 1B, 1A+, 1B+, Zero, Zero W, 2, 3, Zero 2 W) boot from their GPU (not from the CPU!), so they require a non-free binary blob to boot
So the 4 (and I suppose the 5, if it ever actually comes...)
Goes on to say:
> Since then, Broadcom publicly released some code, licensed as 3-Clause BSD, to aid the making of an open source GPU driver. The "rpi-open-firmware" effort to replace the VPU firmware blob started in 2016. See more at https://news.ycombinator.com/item?id=11703842 . Unfortunately development of rpi-open-firmware is currently (2021-06) stalled.
So there you are. Not wrong, are you, but not strictly correct, depending on "...to run properly" definition

How is the free firmware for the Raspberry progressing?
many of those demos work on the the entire pi model range
pi3 support is only broken due to arm side problems, which could be fixed by just using a different bootloader
and the https://github.com/librerpi/rpi-open-firmware codebase can already boot linux headlessly on both pi2 and pi3, it uses a different arm bootloader

Arduino Pro hardware is not open-source hardware
Yes, and some folks are reverse engineering their stuff:

rpi-open-firmware: open-source VPU side bootloader for Raspberry Pi
There is work being done on the RPi4, for example the SHA1 HMAC protecting the boot on the RPi4 had to be cracked (and was easily), I hear future versions have RSA signing support, so the proprietary firmware might become mandatory at some point.

There is a project to create an open source version of the proprietary GPU firmware that boots into the ARM processor:

Taking a Stand in the War on General-Purpose Computing
I note that even the Raspberry Pi is moving towards locked down devices, the RPi4 has an (easily cracked) HMAC blocking booting into the open source firmware and I hear more recent hardware editions have RSA signing support in the bootrom code.
