Do you suggest everyone who has a computer has his own OS? Most people just dont have time (and knowlegde) for this.
holy Terry Davis, orly? why are there so much OS'es? Amiga, Commodore, DOS, numbers of Windows, Rust Redox, collapseOS, kollibri, numbers of Apple, multiple BSD, OS/2, Androids ... ? With next Win11 telemetry it is a ticket to Flossenbürg
Some people build their houses. Some rise their horses. Some make custom bikes, motorcycles. Many write their board\forum software from scratch.
You could pass your own OS you wrote to your granddauther and install in on your husband iPhone as a gift.
