Well, it would be unfair if they changed the rules mid-way
But the doubles players know the rules; you could say 'if they want the higher money, they should concentrate on singles'
After all, I'm sure badminton players would say it's unfair how much doubles tennis players get compared with badminton players
Not trying to be difficult but the doubles players aren't 'entitled' to anything - frankly, I think they're extremely lucky - it's never on TV - it's not in the press - doubles is basically subsidised completely by the singles players
But I guess we've been here before
A good point about badminton. Particularly as in badminton, doubles is as highly regarded as singles, and players tend not to play both events at the highest levels.
Lestienne/Moutet & Barrčre/Halys are now in as alternates replacing Ramos/Zapata & Cornea/Lajovic repectively...

And Lestienne/Moutet will themselves be playing ALTs, as Pel & Stalder have replaced Barrientos & Borges, while Cecchinato & Monteiro have replaced Tommy Paul & Frances Tiafoe.
