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.

Nvidia releases open-source GPU kernel-modules
The carl firmware at https://github.com/chunkeey/carl9170fw should put that argument to rest. That is Wifi firmware source code for the Wifi I currently use.
Easily changed likely means there's a physical knob somewhere that you could accidentially poke as a layperson.
Not that you get a three year CS education, figure out how your distribution packages dependencies, install the correct embedded toolchain (good luck), find out exactly which chip is in your device, fetch the proper firmware source code in the right version, build the thing, figure out how to flash the result onto the chip / read the Linux kernel sources to figure out the filename inside /lib/firmware. That's not easy.
Even if this entire process was packaged (it is--see <https://packages.debian.org/sid/firmware-linux-free>), it probably still doesn't count (or at least shouldn't count) as "easily" changed.

GNU Radio
There are some cards with open source firmware, you might be able to modify it to do something like that.

Dell keyboard comparison.
Years ago someone made a software for testing keyboards and mice https://github.com/ad8e/input-polling-test. Supposedly ThinkPads have around 62hz effective polling rate while someone tested a Dell Precision 7520 and it had 1000hz, which makes A LOT of difference for fast typing/inputs. I'm also a fan of TrackPoint, so if those tests are true, then to many, the last Dell with TrackPoint and 1000hz keyboard would be the best laptop. Could Dell owners make those test to confirm this?

Framework: Open Sourcing Our Firmware
The scrambling is easy to see once you know it's happening: press k and l simultaneously on your Thinkpad keyboard. It'll always come out "lk" unless you deliberately separate them.
Testing was done [0], but it's not written in an easy-to-understand way. As a summary, Thinkpad keys are scrambled within 15-23 ms. Usually, humans ascribe scrambled letters to their own mistakes, but this time it's the keyboard's fault. Lenovo continues to ignore the issue.

Charlie calls out Hasan on Gfuel whataboutism take
You can flash QMK supported kb from 125hz to 1000hz. Most prebuilt keyboard has 1khz these days. You can check your polling rate with this, if you press keys at the exact same time, and there is 1ms delay between them, u have 1khz.
