There was good reason for Kenny to play this exactly as he did, and I don't think the people saying this ruined his game are really thinking about this.
OK, Kenny could have simply said something like "Sure Corinne, we'll vote for you this week, you play it, then we switch over". But that leaves the possibility open to HIM getting blindsided. What stops Corrine from going to Matty and Susie (for instance, or Matty and Crystal, or Susie and Sugar, or whatever) and proposing the same deal, using information that Kenny gave them and portraying him as running the game. This deal with Bob and Corrine cause them to stop trying to search, ensuring Kenny's safety.
That justifies the pre-action, now I'm going try and justify his vote for Matty. We'll split it to two possibilities
A. The Idol is Real
-The result is that Corrine plays the idol, Matty is bounced with three votes. Corrine sees that at least one half of the alliance was truthful, and Kenny at the very least has an in with Bob and Corrine. Likewise, the 4-3 vote, even if they KNOW it was Kenny, ensures that he can't quite go home yet. If Kenny decides not to go with Bob and Corrine, they HAVE to keep Kenny to ensure a majority to boot the other two. They don't want challenge threat and winning player Bob in the F4, they don't want Corrine there, and you need KenCrystal to boot those two. Plus, they kind of have to understand wanting to boot the huge physical threat.
The net effect for Kenny?
-Jury favor among Corrine and Bob, who have influence with the onions.
-An understandable boot of a physical threat for his own game in challenges and for everyone else
-Matty has little reason to hold a grudge, Kenny didn't end up booting him, an idol did.
-Flexibility for Kenny to move between alliances with little possibility of a Dolly-ing
However, we know it wasn't real, so this is his scenario as it happened
B. The Idol is fake
Corrine goes out on a 4-3 vote, leaving an alliance of five and Bob. Kenny may have ostracized himself from his alliance or Matty with his vote, but the net result is the same as if he never talked. However, even if they're upset with Kenny, they still don't have much of a choice unless they can pull Crystal off of Kenny as an alliance mate, or pull Bob over. Neither of those seem particularly likely. Crystal has no good reason to doubt Kenny and she's gone with him on every major vote. And as much as they may want to get rid of Kenny, there's less of a reason to keep Bob. Four winning votes on the jury already and an exceptionally crafty physical competitor who only Matty holds an advantage over. Likewise, if Bob wins an Idol, he may give it to Kenny, or if he keeps it, Kenny looks to be in good position with a bigger physical threat in the game (Matty), friends on both sides, and no good way to avoid a tie vote without Ken.
Net results of this
-Possible distrust brewing by the other tribe members
-A good relationship with Bob as a gameplayer
-The respect of Corrine on the jury, which looks possible to spread to the Onions.
-A perceived weakening of the Kenny-Crystal alliance, which makes them seem less threatening and possibly less of a target for a blindside.
On the surface, it looks unnecessary, but as an endgame move it may be smart. It seems unlikely to me that his alliance has the bravado or correct situation to blindside Kenny before Bob. Also, if you're Sugar or Susie (or even Crystal), you have three choices to boot. Kenny, Bob (who wins the jury easily and can win challenges), or Matty (the biggest challenge threat and a likable person with a good proposal story). Who do you boot? Do you give Bob or Matty a shot in the F4 challenge? Really, it's a symbolic gesture to the fallen Kota who will decide this game.
Edit: I don't know if Kenny wins or not, I tend to think he won't. I just don't think this decision changed anything in that realm. If he gets blindsided by Sugar, I bet it happens if he votes for Matty or not.
