Neutering of a big GC stage should always be a last chance saloon, not something that is done a day earlier just in case. Specially if the reason for worry is something as quickly changing and unreliable as the wind. Maybe the wind would have rendered any serious attacks on the mountain futile regardless , but the way the final climb was taken out just reeks of attitude unfitting for professional outdoor sport.
I think many of us here agree with you.. The UCI already banned high profile rims for safety reasons. Nobody is racing on 50-60s in windy conditions or with lots of climbing.
Temperature does look so serious but @100k winds is an issue, can't really set up the finish line, can't use motorcycles, especially 2 up. Helicopters are likely a no go if it's 100k plus or minus. But setting up promotional stuff along finishing area is too dangerous for assembly and disassembly and chance of big plastic sheets catching wind and knocking things down, seriously considered. And everything is metal, so if that comes crashing down, serious problems..
Emergency response could be inhibited with that type of wind.
