Not sure that Aeroflot's the only one doing this.
Have heard of a UK airline departing an outstation with ice on the wings but electing not to de-ice because the Captain wanted "to get home". Don't have the full details but it was a widebody departing Nth America.
Reasoned, logical thought process by the Captain in accordance with SOP or disregard for safety? I'll never know because I wasn't there.
