Play around with it for a few days.
Spend countless hours trying to get the most mundane things working corectly.
Start dual booting into windows to actually get anything done because you cant be bothered to fuck with linux for 5 hours to get a god damn video to play or sound to work or some bullshit.
Eventually dual boot into windows and never boot back into linux again.
If you cunts stopped ricing your window manager and finding the best shade of pink to go with your anime caricatures and actually spent some time developing a way for linux to use directX you might actually get some users.
Linux can use directx with wine, just not well.
Why do you even need directx anyway though, not trying to defend opengl but seriously what does it matter, video games or something?
