The Sherpas seem to be getting angrier too.

The two sides have been squabbling from the beginning.
I read Tenzing Norgay's Tiger of the Snows when I was a teenager and I believe it was in that book (could've been something I read later, though; it's been a long time) the question came up as to who helped whom up the last few feet to the summit.
Hillary claimed Norgay was too exhausted to make it and collapsed at his, Hillary's, feet as Hillary stepped onto the summit. Hillary claimed that he bent over, grabbed Norgay by the back of his harness and hoisted him up to the top. Norgay pretty much claimed the opposite. Caused quite a lifelong rift between the two and I'm sure lots of Sherpas felt all Sherpas had been slighted. But publicly it was all smiles and cordiality between Hillary and his climbing partner.
Later a spokesman for the two said they had done it together as a team, and that no one was first and that no one carried anyone.
