That's such a weird one.
Hamilton entered the corner defensively, but despite steering as much as possible to the right (F1 steering racks are not particularly good at tight arcs; the teams fit a different rack for Monaco where a much tighter arc is needed) and not being on the throttle, thus taking the maximum angle through the corner, and leaving a car's width to the kerb on the outside (the only time it's less than this is during the collision, when Hamilton's front-left under-rotates due to the friction with Albon's front-right, sucking the car to the left), the cars have become entangled.
Given that the front of Albon's rear tyre hit the rear of Hamilton's front tyre, I'm not sure what Hamilton slowing down would have done except make the collision happen sooner. Albon certainly had the width of a tyre of space to his left he could have been in, though it would have put him on the rumbles.
It surely has to be a racing incident. Hamilton could neither turn more nor slow more, and Albon could have done more to avoid it but had the position and can't have known Hamilton's car would have been on that path because it was at its turn limit.
Still, after yesterday's silly conspiracies about Hamilton not getting a penalty in qualifying because he's the favoured golden child of F1/Mercedes/BLM, he now has one he most certainly deserves and one he probably doesn't.
Oh, and drivers not taking the knee were doing so because although they might believe that racism is bad on an individual basis, the knee has become a symbol of the Black Lives Matter organisation (which is a pack of bastards) rather than of the black lives matter movement/slogan. They support the message (hence the t-shirts) but not the group.
