Too many permits given out.
I went to Nepal at the beginning of their VISIT NEPAL 2020 campaign. It was massive. So was COVID-19 a month or so later... and then tourism ended for years. Huge losses and economic smashing.
Nepal reopened and set new guides to hikers rules, but also allowed more permits. China never will allow many laowei to climb that face, so the foreigners have to go via Nepal. Nepal and its people need money. Over-crowding and rushed expeditions tarnish an amazing place and wonderful mix of cultures. Everyone who climbs wants the big one and rush in, rush out. Perhaps, it is better to take some time and see the other peaks, views, and support the hobby with unique views. Possibly.
