That's how computer hardware used to work: see "IBM PC". I have no idea if it still works that way. I haven't seen the insides of a computer for ages now. Hardware is constrained by the costs of manufacturing at scale. I can't make my own computer as I want it (can't find a hand-cranked punched-card reader, or a steam-powered dot matrix printer. Oh why). With software though, everyone can write whatever they like and send it out there were someone is bound to pick it up and reuse it. A little like the way Covid-19 spreads, I guess. No constraints, no respect for specs.
