I think BWF really needs China, their main job is to promote badminton. Who are the stars? most are from China, not to discount Malaysia, Indonesia, Denmark, Korea, etc. But we have to admit badminton icon country today is China. If somehow this country show some action like refuse to take part for any international matches like SS, OG, etc. The image of badminton in this world would be greatly discounted. Imagine no more OSIM sponsorship.
No one will go to stadium and buy ticket to watch badminton, no one will turn on their TV for matches cos no commercial sponsorships. Maybe i have exaggerated a bit here. But i am trying to say, BWF needs powerhouse country like China. Having them weakened by using bwf points doesn't help much.
Btw, ex national player Li Ling Wei is an executive inside BWF.
