Candide Thovex crashes into a skier - Who's Fault?

It is April Fools, however this is probably real. The favorite ski video maker Candide Thovex is shown wiping out a skier, who appears to be just standing at the landing.

Who is in the wrong? Candide says "Landings are for landings." Not much detail about this one, I'm sure more will come out. Was the skier just standing there, or had they just crashed and were also getting up, getting ready to move?

What if it was a 6 year old?
