Does anyone here pay less for a boring movie or a shorter movie or just a plain stupid movie at a theatre, than for a worthwhile movie? "Entertainment" value is subjective.
Believe it or not, there are some people who would prefer to watch women prancing around the court for 1.5 hours in sportswear and get much much more out of than than watching what most here would call high-quality tennis in a men's 4 hour nailbiter.
That said, just live with it. It's not going to change.
Equal work for equal pay.
Women should play best of 5 sets then.
Believe me, this is not something anyone really wants. 3 sets is enough.
