That can only be Aeroflot, 'kings of snow and ice'.
Anyway, it's difficult to asses if it's just powder snow or snow with ice underneath. In our company this is not allowed. Takeoff with frost, ice, snow or other contaminents on critical surfaces, flight control or lifting surfaces are not permitted. All vents, inlets, control-wing surfaces and horizontal stabiliser must be free of any contaminents.
I would not feel safe as a pax seeing that much accumulation. Never seen it before either where a crew actually departed. Very little to gain by not de-icing and a lot to loose. First thing that came to mind was the 737 taking a bath in the Patomac...
Anyway, a sad day for aviation to see a genuine operator do this.
