Except that yielding to the pedestrians is exactly what they should have done. You don't cross into the wrong lane just because you don't want to pause for a few seconds to let the pedestrians cross.
I didn't speed up in order to brake suddenly, I was proceeding through my green light into my lane that would have been clear had the other driver made her turn correctly. I mean, are we all even watching the same video? I didn't start moving forward under power again after pausing for the pedestrians until the van has crossed my path. There was no "sudden braking" whatsoever...I wasn't even in the throttle as I approached the intersection.
