As someone who used to play a lot of poppy, she used to be op. However, the nerfs left her in a terrible state. She's slowly recovering with slow buffs right now. She doesen't counter much people except champs with dashes and you played Yasuo, of course you're gonna have a bad time. Literally, all you had to was wait for her w to be down as it does not last long before dashing and you'd be fine. I could understand pre-nerf Poppy one-shotting people as she was broken (rip bae) but Rito nerfed her burst a long time ago. They changed her q to deal more%health dmg and less flat so she could not burst squishies as hard but deal more dmg to tanks. This meant that getting oneshot by one is impossible unless it was AD poppy, You were really low, you are a salty yasuo main, or you were incredibly behind. Additionally, Poppy gets no dmg rewards from building tanky, all her dmg abilities scale with ad except w. The only tank items that give her dmg are sunfire, iceborn, deadman's, and thornmail. These are all items available for everyone! So, she DOES NOT gain damage rewards for building tank. She gains tankyness which allows her to stay alive longer to do more damage, but in a slower pace which disproves her one-shotting some once again. Additionally, if you're complaining about Poppy's base dmg, then you'd have to lower the base damage of all tanks as most tanks, have decent base damage while having better cc than Poppy. The only thing that sets people apart from Poppy was the fact that she was a jack of all trades tank pre-nerfs, but now she's just peel bot. as her DAMAGE and ENGAGE WAS NERFED A WHILE AGO. So, I don't see the point of how post-nerf Poppy could ever hope of one-shotting a yasuo as she is not the champion she once was. If you want Poppy to be nerfed even more, what can a tank with even lower base dmg, a very situational stun, okay-ish cc, and positioning based dmg do?
