I must say Massa's comments about his pit crew are, in my view, disgraceful. The concept of time "lost" in a pitstop is, of course, by comparison with a near perfect, sub 3s stop. By that standard, you can say the stop cost him about 4s. But if Massa wants to apply that standard, he had better make sure he has a near perfect race, otherwise we can start to analyse how many seconds Massa cost himself.
He lost a hell of a lot of time behind Bottas and, for my money, he was lucky not to lose more. The reason Bottas wasn't willing to let him go when the team asked him is that Bottas knows team orders are a one-way street at Williams. The precedent is that they don't apply to Massa. So Bottas cannot be expected to think they should apply to him. Perhaps if Massa hadn't placed himself above the team when squabbling over seventh in Malaysia, he wouldn't have found himself impeded and obstructed on his way to a possible victory.
At the end of the day, members of the pit crew never approach journalists and slag off their driver when he costs the team time, even if they themselves have done a flawless job. It must be incredibly frustrating for them to be working with a driver who blames them for costing him a few seconds when, in the space of 22 laps, he can't pick off six cars, all except Bottas and Hulk virtually lined up in front of him, when he had tyres thirteen laps newer than Bottas, seven newer than Hulk, twelve newer than Vettel, fourteen newer than Bottas, eleven newer than Ricciardo and four laps newer than those on Rosberg's crippled Mercedes, on possibly the least difficult track on the calendar to pass on.
He only got Bottas and Hulk because they went off fighting each other, he couldn't get Vettel because he allegedly couldn't remember what button to press or when, and because he was shockingly poor on traction out of the hairpin. And then when Vettel got past Perez, he crashed while trying to do likewise (albeit that Perez was culpable in that situation). He was certainly a bit unlucky that it ended as it did, but by the time the crash happened his shot at victory had already passed him by, not because of the slow stop, but because he hadn't been able to clear the slower cars ahead of him. None of that does anything to dispel the notion that he's not a particularly good overtaker.
