"X's counter is hard CC"

I see this a lot when looking at threads that talk about typically hated champions in League (Yas, Zed, Riven, LeBlanc etc.), but um....sans an ulting Olaf, isn't everyone's counter "hard CC"? Stunning a champion stops them from doing what they're supposed to do 100% of the time so of course doing that is the optimal away to counter a champion, but that doesn't mean it's their only counter. You can kite Darius, you can dodge Ezreal's skillshots, you can punish Draven when he goes to get his axes, etc.

So when people say "X's counter is hard CC", doesn't that translate to, "I can't think of anything that can actually counterplay X"?

I'm not necessarily saying that there is nothing that can counterplay X but if that's your only answer to "X is broken", maybe you aren't necessarily qualified to talk about X?

EDIT: I realize I forgot to take Tenacity into account which takes away from what I'm saying a little bit. Basically this post was targeted at the fact that I personally don't think "hard CC" is a substitute for counterplay.
