I advice you to reread the post.
He's overloaded but isn't overpowered

I think it's more like unbalanced and slightly overloaded, but has everything you don't want a champion to have when put together.
LOL the clickbait. His kit IS overloaded, but it needs to be. Anyone who is a melee damage carry needs to be overloaded, simply because they don't have the safety of range. If you look at Camille, her kit is overloaded for the same reason.
Where did Riot say this?
They used Tryndamere as an example of this not Yasuo. No where do they say Yasuo is overloaded but not overpowered, they said he's a windowed champion. You must have misread OP.
Meanwhile, Yasuo is a prime example of a champion that is heavily windowed in lane. Even when he’s trading on his opponent, he generally needs to regenerate resources before he can land a kill. His Way of the Wanderer (P) shield and the internal cooldowns on his Sweeping Blade (E) make it so that it’s unlikely he can brute force a kill by just sticking to a target (not until later when he has a lot of items, at least), since his advantage isn’t perpetuated by being in melee range. I don’t think we’d call Yasuo the epitome of laning counterplay (he can feel like a hard counter in some matchups), but we do think his kit does a lot well in terms of windowed power.
Yasuo is brain dead to use.
