who the hell thought it was a good idea to make a champion's Q not R , Q so powerful ?
while 
R can't even kill a champion at certain health
Kite, hard cc, group with team, bait him.
Yi is predictable, easy to lock down, save your hard CC for him.
Exhaust him, or just win the game before he can pop off.
3500 gold item death's dance, + 2500 for his jungle item is plenty of time for you to win the game to the point where Yi is irrelevant anyway
There isnt really a direct way to counter Yi himself. His biggest weakness is overconfidence. In games with Yi, generally all the kill gold is funneled to Yi, and he becomes the only relevant player on the team. If he messes up, its likely that it will cost him and his team the game while they wait for him to rez.
What I see people saying is that Yi is basically +5 on the enemy team. Kinda like how Garen seems to be now. One player is a +5, and that's okay. Build around them, and win. They say. But imagine a team with two polar opposite +5s. Yi is just that thing that needs to end. The handful of raidboss champs in the roster need to just end.
pure damage counters yi. put in heal reduction to negate deaths dance. plus a nullifying CC in there also screws him up.
Grievous wounds.
Positioning.
Understanding that his Alpha strike makes him attached to the first target and abusing that by layering CC when he pops out or flashing under turret or some other bad spot.

Thank you all
This is gonna come off toxic because its so overused and usually used in a toxic context -- but I assure you I mean no offense.
Get good.
No seriously, once you figure yi's kit out, its pretty easy to play around. Don't blow any gap closers or hard CC until after he alpha strikes. Don't blow big cooldowns on him while he's meditating. Don't try to run away from him when he's ulted.
80% of the problem players have with yi is that they've never played yi and don't know what yi does. Learn his kit. Play 20-30 games as him, figure him out.
Low elo yis carry games because people have dog shit positioning and leave themselves open for him to just come in and clean house. Low elo players over extend in lane, don't leave themselves an exit, stick around for WAY too long with low health and no flash, etc etc blah blah blah, the list is long.
Low elo players burn all their cooldowns right at the start of a teamfight trying to get the 100-0 wombo combo all on one or two targets, rather than using their skills efficiently throughout the fight, and leaving one or two big CC cooldowns just in case they need to disengage or peel.
That's where Yi thrives. When all the CC is burned and the fight devolves into people chasing each other with auto attacks and half-healthbars.
A good yi knows he doesn't need to be in a fight until basically after its over. He's the janitor. The cleanup crew. When everyone's blown their load and nobody's got anything left, Yi goes in to an all you can Yi buffet.
So the answer is "Get good."
Don't blow all your shit right at the start of the fight. Don't over extend. Build some armor. Know Yi's kit so you know how to exploit it and outplay it. Don't hang around with 20% health. Don't chase.
Basically don't invite yi to come screw you over, and yi won't come screw you over.
simple answer; you cant counter him
It says a lot when the only person who agrees with you is a guy with the word troll in his name.
You need a team with a bunch of CC.
CCing him is the obvious and most cited example, but really any disrupting CC and well-timed burst will fuck him up. He can't do much unless your team is already low enough for him to clean up, so try to avoid fighting until you've taken care of him.
