Agree with this argument 100% with respect to any commercial broadcasting entity that's bidding for the rights, and thinking about selling advertising time and/or subscriptions.
Does it apply to the BBC though, as it's currently funded? Both Men's and Women's World Cup finals are listed events, so it's not like they have to compete with pay services - whoever wins the rights has to make the games available free-to-air. Not saying that an equal fee is appropriate, but reports seem to suggest that they're offering 10-20x less.
Supposedly viewership for the Women's Euros peaked at 17.4m - which wasn't that far below the peak TV audience in Qatar (21.3m), and more than half what the Men's Euros final pulled in.
I sure as hell don't want them giving taxpayer money to FIFA for no good reason; but it does look like the BBC are offering an order of magnitude less in what is basically a closed bidding process. I'd probably be pissed if I was a female footballer......
