I don't see where they were misleading. Maybe they could have communicated more clearly, but the ranch being concerned about hiker safety is no reason to invent other lines of reasoning and throw them under the bus.
In hindsight, was it safe? Probably. But you can't blame the ranch for covering their ass.
From the CAIC:
On Saturday February 2nd there were at least five avalanche incidents across the state from the Wyoming border to Silverton in southern Colorado. There was one fatality, and several people with reported injuries.
The current snowpack across Colorado is in a delicate state of balance. Before the last storm cycle moved across the state the base layers of the snow were exceptionally weak. The new snow during the storm came in with significant wind and a high water content, meaning the new snow was heavy, and developed quickly into dangerous slabs.
I'd just be thankful they didn't cancel the trip(s) altogether. Congrats to all on a rare winter summit.
