This video only tells the second half of the stories.

I think the first half goes something like this. The Euros wanted to bend some mountain rules like the routes and the gears. They wanted to climb in their own ideas. The conflict broke out at the top and couple porter/guides sherpas were beaten by those goras in the mountain top.

The brain does not work at its 100% at the top of the mountain and you add the EGO and those climbers life time investment of $$$ and emotions and then the strict guidelines Nepal Government imposes sherpas to keep the mountain climbing as safe as it can be, the result was obviously nasty.

Not every climbers aholes but every now and then we do get some racist aholes who just want to treat sherpas like slaves rather than a mountain ranger. These climbers in particular used racist words to them and then brawled at the top. When they decended to the base, sherpas told more buddy of theirs and this was the second round of a$$ whoppings !!

I do not cheer what sherpas are doing but there is always a two sides to the story. I personally have only met one sherpa ahole in my life and i am not going to generalize whole sherpa for his action.

By the way...not every mountain guide must be a sherpa anymore...lots of Lamas and Tamangs have been opening trekking/porter shops lately.
