Just to finish off then:

The responsibility not to hit someone is that of the Captain.
I absolutely agree. However, the point remains that the captain has the right to expect that clearances are adequate if he has been cleared along a taxiway by a controller, particularly if he cannot see his wingtip. That is why the clearances exist in the taxiway system, and if you bother to look up the CAP references I provided above, you will see the specifications for yourself.
So, please explain to me, in the case of an aircraft hitting a vehicle that neither of the pilots could see, with a wingtip that neither can see,
why the captain is at fault?
At the end of the day, the 767 pilot will no doubt shoulder some blame. Maybe he was trying to squeeze past and muffed it, who knows? However, there are other failures in this incident as well, and to simply dump it all on the 767 captain is missing the point in a big way.
