A brother I knew turned down a career with an Australian basketball team (I know, not quite US standard) as he was studying and got baptised instead.
Prince, particularly in later years, acted in a manner at his concerts that few JWs would get away with.
As far as I’m aware, Serena was never baptised, so little can be done to stop her giving glory to Jehovah for her wins. Publicity nevertheless that helps JWs become known
I agree that the situation of Prince in particular makes mockery of experiences of brothers that felt compelled to give up fame based careers for their Watchtower beliefs.
