Some people don't like her getting wildcards but who wouldn't give her a wildcard? She is one of the most famous athletes of all time. Everyone knows the Williams sisters and I bet her name in the draw still sells tickets.
From that perspective we should hand out 25 WCs per event, allowing even Mac and Navratilova to play.
If we wanna turn tennis into an exho circus.
But pro tennis needs to be primarily a serious competitive sport, not a circus trying to make money out of players who can't win even one match.
She can play exhos if she "enjoys" tennis so much. She can make good money that way and offer fans more value by playing vs equals.
Pro events shouldn't be part-exhos. It takes away a bit of their legitimacy. I'm not saying one player like Venus getting tons of WCs and never winning will ruin the credibility of the tour, obviously not, I'm simply addressing your point that money is the only concern. It's not. The WTA anyway doesn't depend on Venus to continue being successful...
The argument that "it sells tickets" doesn't work. Otherwise let's have strippers and dancing bears too, that would draw in huge crowds...
