WNBA doesn't hurt or harm me in any way. I've got hundreds of other TV channels and no one has ever forced me into an area to watch them. If someone (the NBA) wants to pay to keep the league afloat, good for them! It's their money, they can do what they want with it.
There's other businesses I don't frequent - and for most of them, I don't care if they stay open or close either, or what it may be costing their owners to remain open.
