>Some may point to the existence of the Raspberry Pi as a counter argument. "Here is a computer built by a small company that is designed for tinkerers," they might argue

LOL. the Pi? its entire SOC is controlled by Microsoft ThreadX. if there were ever a better example of how the war on general purpose computing was won its the Pi. You only ever emulate or virtualize linux on it. the kernel is never aware of the threadx hypervisor and no open alternative exists. the officially supported OS developer just recently back-doored a repo and GPG key onto every one of them during an upgrade.
