Preity Zinta herself updated the post snd removed the 'camera angle', while she says she spoke to Karun and he said it was a six, who's verifying all this?
Thankfully the umpires don't take the fielder's words now and go for a check, they didn't find a conclusive evidence that Karun touched the ropes before releasing the ball (his toes might have touched the skirting, but the camera angles didn't show any of them moving before the ball was released),
a decision that went in favour of bowling team (umpires are bashed when it doesn't).
That was the last ball of the over and the relevant team was asked about timeout which was subsequently taken, even PBKS had their strategy making meanwhile the decision was taken upstairs, they didn't oppose proceedings.
Thankfully the game is played in its own way and not influenced by random social media postings
