I have a legitimate question about Ornn

So the question that I would like to ask the general community and any riot employees who decided to read this is why can windwall cancel ulti. The reason I ask this is while yes I did in fact loose a game to recently (guilty as charged) but it is really frustrating. I mean is that not the same kind of interaction as when could be knocked out of her ultimate in the past with like say a W (which is her aura that prevents dash and stuff like it). Plus when you also think about it from a gameplay perspective it does not really make sense

gameplay wise it is not only really frustrating to go against but yas windwall has a much lower cool down that ornns's ult. There is also that fact that when you think about it ultimates are supposed to feel impact full in league but his can just be canceled with an ability.

I feel like this has been talked about and discussed before so I apologize if I'm repeating something. Also while it is on interaction with yasuo its a really unfun one especially when your in a team fight and your ultimate gets completely canceled out before it can even do damage in some scenarios.
