Cycling is a different sport than running because we banned bikes in one of them. Both sports have lists of things you are and are not allowed to do in order to maintain the spirit of the sport. As shoes become more advanced hundreds of jurys look at the new shoes and decide if they are allowed or not. Most shoes pass but some are banned.
In the engineering example they are allowed to use calculators in their job but they are not allowed to use them in math competitions that don’t allow them.
Grammy is a competition and not part of their real job. If you don’t want to participate you don’t need to.
