It's as if saying the moon landing wasn't impressive because it was financed by the USA and used as a propaganda tool. "Its simply money"....
The dude climbed FIVE 8k peaks in LESS THAN 2 WEEKS (12 days). That alone is absolutely insane.
Messner could make the same ascents today at 70+ years old given all those advantages. But Messner did it all 40 years ago, leading the climbs himself, without oxygen, and often on new routes/first ascents.

What you praise on him is praising money :-/

Please go check and read mountain community opinion on him.
