1. Tiger has 10,000 people following his group, and because he hit his ball outside the ropes he was surrounded... 5+ people deep on all sides and he's 50 yards from Sergio. Discreetly parting the crowd to see where Sergio was would have been like parting the Red Sea (ie. impossible even with supernatural help).
2. Tiger can not see Sergio.
3. Tiger pulls a club like he did 70 other times during the round. and like a bunch of Bethpage Drunkards, the crowd makes noise. Even if Tiger was to anticipate the crowd's reaction, his reaction says otherwise (as noted by eye witness bystanders). He gestured to the crowd to quiet down, at which point he was told by a Marshall that Sergio had hit already and he was away.
4. The crowd started making noise well before Sergio started his backswing. Not at the top... not at the start... not at impact... but WELL before. If he was disturbed he had ample time to back away. Watch the tape.
5. Sergio never said anything to Tiger's face, but instead chose to go to the media. Tiger didn't know Sergio was spooked by his crowd, he was never told of the issue by Sergio, and therefor never knew it occurred... remember, as far as Tiger knew Sergio had already hit. It is very difficult to apologize for something that you never knew about, and that your playing partner failed to mention while you were playing.
6. Sergio has a history of being a crybaby.
7. Tiger has a history of being a responsible playing partner (note he marked his final putt on Sunday so his partner could finish without fighting the crowd noise).
Haters always need something to hate... but this whole scenario is a real stretch. Tiger did nothing wrong and even if he did, he was never aware of it, nor spoken to about it by Sergio.
Whiners gonna whine.
Winners gonna win.
The whiner whined and the winner won.
