Maybe you are correct on your first sentence.
Regarding Williams no one can deny she has been a great player, but she's not the GOAT, she's 10 years older than Steffi Graf was when she retired, and she has one slam less, I think, maybe if she had hung around might have won another half a dozen, that's history, her game is based around power, not necessarily skill, no one is bigger than the game, sometimes I think she thought she was
She is still within her rights to play until she is 60 if she chooses, but maybe the fact that a player so low in the rankings playing someone else even lower on centre court seems preferential treatment that now is more deserved for higher ranked players, no one is bigger than the game.
Sometimes it's not what you do or what you have that defines a person, it's what you are.
