GNU/Linux has trouble, but thanks to Android (and ChromeOS), we know Linux itself specifically on ARM does actually work. Freeing those drivers is another matter, unfortunately.

Webcam firmware & colour grading & programming is a black art btw.

Those are specific firmwares for those devices that are either closed-source binary blobs, open-source hackjobs/reverse engineered attempts, or just plain missing firmwares. The fault is not on Linux but rather on Qualcomm not releasing things for that specific SoC. Some SoC's have better support than others. ARM cpu's themselves works perfectly fine on linux.

Intel has closed things down: some wifi and webcam firmwares are poop and a massive pain to get working on newer chips (if at all). Their wifi firmwares also don't respect certain kernel overrides (which is why I replaced my Intel Wifi 7 chip with a mediatek Wifi 6 one). Blame is 100% on intel and not linux. Broadcom is also pretty bad at being a team player in this regard.

I basically recommend everyone to stick with AMD chipset & GPU's where possible, because they have mainline kernel support nailed down 95% of the time.

Again, ARM works fine, their extra firmwares for extra devices on SoC's are to blame if you struggle.
