I don't understand the conspiracy theories. With 7 laps to go Glock was in 7th place, 20 seconds behind Hamilton, and completely out of the picture. Because Hamilton (and everybody else who wasn't driving a Toyota) came in for tyres, Glock passed him in the pits.
If there's been some conspiracy, all Glock would have had to do would be come in for tyres, just like everybody else. He'd have come out 20 seconds behind Hamilton and wouldn't have been in a position to challenge him.
Toyota took a simple gamble, that the time they gained by not pitting would be greater than the time they lost by running the last few laps on the wrong tyres. It actually worked in that Glock finished in 6th, rather than 7th, and 4 seconds behind Hamilton, rather than the 20 seconds he'd been behind when everyone started changing tyres.
