As much as I share this sentiment in general, in this case its probably more likely that this has something to with liability if something goes wrong with the implant. And I would bet the company never released the schematics and code so that aint helpin.

Could prob be solved if implants would be required to be open source so that third party servicing could happen.

Since you want an arch based dostro, i can highly recommend EndevourOS. Its comes with an easy to use installer, many desktop env options and a few quality of life tools like a comandline tool (nvidia-inst) to install nvidia drivers. And if you choose KDE Plasma in the installer, it will default to wayland.

AMD is still by far the better gpu choice for linux, but since explicit sync support is now in the 555 nvidia driver and kde plasma 6.1, most problems that nvidia had (i had) with wayland have seemingly just vanished. So no need to imeadiatly buy a new gpu.
